How to Build an Astrolabe (WIP)

Step 1: Get overly invested

Step 2: Madness

[patricia-taxxon]

it's clear why flat earthers chose the azimuthal equidistant projection for their map, cus its the one that lets commercial flights go all around the earth without teleporting by just going in a circle around the north pole. but like, why center it on the north pole? why is antarctica the one that gets stretched out into the barrier between terra & infinity? it's gotta be northern hemisphere bias, like if a majority of flat earthers lived in australia or south africa or southern argentina/chile then they'd pick the other pole to be the ice wall.

(Currently a tie between the Podcast and Zine Map~)

I looked for map references and fell back on Avenza again: they really are a valuable vintage map resource. Cannot recommend highly enough. (Also their digital maps are georeferenced!) They don't have geological maps, but they do have a few styles of world maps. I'm going to hop back into SSkies to get a better idea of where the climates, orientations, and geological formations are~

[o-craven-canto]

Highlights:

CYLINDRICAL (meridians are equally spaced vertical straight lines, parallels are horizontal straight lines)

Equirectangular (ca. 120 CE): my favorite! X-Y coordinates on the map correspond exactly to latitude and longitude on Earth's surface, simple and straightforward. Parallels and meridians are all evenly spaced perpendicular lines. Doesn't preserve perfectly shapes or relative sizes, but approximates both.

Cassini (1745): the equirectangular projection, if first Earth is rotated 90° so that the central meridian becomes the Equator

Mercator (1569): gets a bad rep because it inflates areas at high latitudes (so mostly northern continents, since the southern are close to the Equator). In fact, it cannot show the Poles because they'd be infinitely far away. However, it perfectly preserves shapes and it's useful for navigation because sailing with constant bearing always traces a straight line on this map. Some variant of it is used in most web maps.

Gall (1855): variant of Mercator's that can actually show the poles. Landmass shapes are no longer perfect.

Gall-Peters (1855): kinda the reverse of Mercator: they sacrifice landmass shapes to preserve perfectly their relative areas. Landmasses near the Poles are squashed rather than stretched infinitely. Lambert (1772) has a less extreme version.

PSEUDOCYLINDRICAL (the central meridian is a vertical straight line, but other meridians may be curves, though still equally spaced on any given parallel; parallels are still horizontal straight lines)

Ortelius (1540): preserves neither shapes nor areas, but compromises between both. All meridians except the central one are arcs of circles.

Mollweide (1855): preserves relative areas. Fits exactly in an ellipse, and all meridians except the central one are arcs of ellipses.

Collignon (1865): triangle. Preserves relative areas, somehow.

Goode Homolosine (1923): preserve relative areas and keep landmass shapes reasonably well, at the price of cutting huge gashes through the oceans.

Loximuthal (1935): constant bearing lines are straight lines on the map, like in Mercator. Preserves neither shapes nor areas. Weirdly asimmetrical hemispheres.

Robinson (1963): preserve neither shapes nor areas, but approximates both quite well. Kavraisky has evenly spaced parallels. The similar Equal Earth (2018) preserves relative areas.

CONIC (meridians are converging straight lines, parallels are arcs of circles)

Equidistant conic (ca. 150 CE): another of the old ones. Preserves only the distances along meridians, like the equirectangular.

PSEUDOCONIC (the central meridian is a straight line, the others may be curves)

Nicolosi globular (ca. 1000): splits the map in two circles, replicating the feeling of watching the world from space from two sides.

Werner (ca. 1500): heart-shaped, preserving relative areas, with the parallels being concentric circles around the North Pole.

AZIMUTHAL (meridians are straight lines meeting at the center, parallels are concentric full circles)

Gnomonic (ca. 580 BCE): probably the oldest map projection. Unfortunately it can only show at most part of one hemisphere, with the Equator being infinitely far away, much like the Poles in Mercator.

Stereographic (ca. 150 BCE): as before, but only the opposite pole is infinitely far away. The far hemisphere is still distorted, so it's still used in two parts, each centered on one pole.

Orthographic (ca. 150 BCE): basically just what the Earth would look like if observed from infinite distance: it shows exactly one hemisphere.

Azimuthal equidistant (ca. 1000): all parallels are full circles centered on the North Pole, and the South Pole is also a circle surrounding all. The map used on the flag of the United Nations. Most Flat Earthers think the Earth has this shape.

Two-point equidistant (1919): preserves distances on the straight line that passes thrrough two arbitrary points. A favorite of history atlases: it's usually used to portray Asia with as little distortion as possible despite its unfortunate proximity to both North Pole and Equator.

Hao projection or plane terrestrial globe (2002): popular in China, replicates as much as possible the curvature of a globe.

PSEUDOAZIMUTHAL (central meridian and equator are straight lines; other meridians curve toward the central meridian, other parallels curve away from the equator)

Wiechel (1879): the meridians form a pinwheel! Preserves relative areas, but which great distortion of the opposite hemisphere.

Aitoff (1889): looks like the Mollweide with diverging parallels. Mostly relevant because of:

Winkel Tripel (1921): arithmetic mean between Aitoff and equirectangular; the map used by National Geographic.

OTHER

Peirce quincuncial (1879): a perfect square that can be tiled regularly in all direction. I think Flat Earthers should start claiming that Earth look like this and that there are infinite copies in every direction.

Van der Grinten (1904): built ad hoc to map the Earth onto a circle, preserving exactly neither area nor shapes.

Craig's retroazimuthal or the Mecca Map (1909): looks crazy, but preserves the direction from any place on Earth to one specific point; in fact it was invented to help Muslims find easily the direction to the Mecca.

Cahill's Butterfly (1909): adorable, and can be folded into a perfect octahedron.

Dymaxion (1943): approximates shapes and areas, and preserves close connections between continents, at the price of a really weird shape.

[ben-101-rewrite]

So what are the other Azmuths like in the re-write? I don't really like how in canon alternate Azmuths are "Too smart to be evil", which is a bit of a blanket statement and doesn't get into specifics.

I presume you mean the Azmuths from the different timelines I made up for the Eon Vs Ben fight, so here is a summary for what I think I might make them. Prime Timeline - You know em, you love em, good old classic Azmuth. Grumpy but means well. Gwen 10 - Similar to Prime Timeline, just now has to deal with Gwen. Ben 23 - After finally building a bridge with Ben 23 thanks to Ben Prime, Azmuth has decided to move to earth with Tetrax and Sixsix to help as mentors for the kid. While similar to the Prime Timeline, he has a lot more patience, coming across as more of a tried dad if anything. Ben 10K - Similar to Prime Timeline, and the sort of man in the chair for Ben 10K, being more involved in helping out, him and Ben having deep respect for each other. No Watch - Gave up on the omnitrix project really early, and lived life as a hermit. He's kind of just depressed, living alone without anyone, including people like Zenith or Myaxx. No Watch Ben meets him on a plumber mission. Omni Ben - Basically Omni Ben's father, being called so by Ben himself. He starts off as being rather protective, having sheltered Ben his entire life out of fair of people wanting to abuse his power, but mellows out enough to let his son stay on earth. But he does visit a lot, making sure he's living well. Jen 10 - Just a genderbent version of Azmuth, a female galvan by the name Azimuthal. Julie 10 - Him and Zenith never broke up, and instead made the watch together, living life as an old married couple. They're amused by watching the dynamic between Ben and Julie, being mentors for the both of them. Sentient Omnitrix & Ben - Similar to the Prime Timeline, just now having to deal with the omnitrix becoming sentient. Rooters Ben - An official member of the Plumbers. He's a high ranking member, originally making the omnitrix to be given to an Alpha Plumber leader, only for some chaos to lead it into Ben's hands. He does his best to be a good balance in Ben's life, wanting to make sure the kid doesn't go down too dark of a path. Eon - Dead, like everyone else in that timeline. Bad Ben - Has a reversed alignment. He's cold, uncaring, and is willing to sell anything he makes for the right price. He gave Ben the omnitrix in an agreement, using Ben as a sort of guns for hire and bodyguard when he needs it. Doesn't care about the harm he is causing others as long as he can do what he wants. Mad Ben - He had tried to send the omnitrix to Max in order to stop Vilgax, but it failed, with Vilgax now mentoring Ben as his heir. He's currently on lock down by Vilgax, knowing Azmuth is too dangerous to have running around. But the First Thinker is the prime recuse target for the resistance. Azmuth hopes that, if he can escape, he can try and bring sense to the host of his omnitrix. Negative Ben - Albedo is the first thinker on Galvan Prime. Azmuth has become washed up, sticking to the background. He is aware that Ben has the omnitrix, but he's too afraid to talk to him, blaming himself for what happened to Ben's family. Benzarro - Working alongside Vilgax, but begrudgingly. He's still hoping out on a way to unfuse Ben and Zs'skayr, but knows he might need to find a way to stop him and Vilgax when the time comes. Malware - Dead during the accident between Ben and Malware. Forever Knight Ben - Was killed by Ben when Azmuth and some of his men tried taking the watch. Fusion Ben - Never met Ben, and thus is still currently a hermit, uncaring towards what is going on with the watch. He isn't even aware it's currently broken. Ultra Ben - Kept on lockdown by Ben, who doesn't want to hurt Azmuth, but can't let him walk away, due to his knowledge on the Omnitrix. Has tried many times to convince Ben to stop, but it always fails, so now he's trying to find a way to stop him in secret. Light Magic Ben - Old wise wizard, having tutored Ben early on. He blames himself for what happened to Ben, and has been hunting down a means to 'cure' the boy if he can, even looking into some forbidden magic with Gwen.

riemann spheres as a fundamental type, pt.1 basics

ive been thinking on and off about riemann spheres for a while now, a couple weeks really, and so far i think there's some utility to them as a building block of a type system of some kind for a joke/toy computer language

background: riemann spheres are a neat tool in complex analysis where we imagine a sphere whose equator intersects the complex plane, and every number on the complex plane is representable by a point on the sphere such that a line is projected from the north pole and through that point onto the complex plane. naturally, this means that the north pole is P(∞) and the south pole is P(0). see below how that would look like with other unit points of the complex numbers

a neat thing the riemann sphere allows us is to define meaningful division by zero so now z/0 = ∞ clean and simple! and also its inverse, z/∞ = 0 is well behaved as well. this simplifies doing complex analysis but stereographic projection is an absolute bitch to work with turns out, and doing arithmetic on points on the sphere is a mess because it's not a linear mapping (it's continuous though so that's fine)

if we're dealing with ONLY real numbers in relation to a circular slice of the riemann sphere, it already starts looking like a mess; for any number n∈R its projective cognate on the circle is located at (2n/n²+1, n²-1/n²+1). on the real riemann sphere though? zoo wee mamma

an arbitrary z∈C, represented as a point (x,y) on the complex plane, has to walk through a rather ugly mapping (related to the previous one) to find its point on the sphere; more accurately, given the coordinates (x,y) of the point on the plane, the point on the sphere is located at (2x/1+x²+y², 2y/1+x²+y², -1+x²+y²/1+x²+y²), which is godawful in spherical-to-polar coordinate terms, this is much simpler; for a polar pair (r,θ) the point on the unit sphere representing it is (φ,ξ) = (2*arctg 1/r, θ); and conversely projecting from the riemann sphere is also dead simple, given the zenith-azimuth pair (φ,ξ), (r,θ) = (ctg φ/2, ξ). of course, translating from polar to real coordinates is ALSO dead simple; x = r * cos θ, y = r * sin θ. if a computer system were to store complex numbers (or any coordinate on a 2d plane really), it makes sense to store them in terms of spherical coordinates of a riemann sphere, since this makes infinity well-behaved as a unit (zenith = 0, azimuth = literally who gives a fuck) and is surprisingly efficient. knowing that the zenith is ∈[0,π] and azimuth ∈[0, 2π] can allow for some formidably dumb optimisations that can save on space and ensure granularity. compared to storing them as 2d cartesian or polar coordinates, this provides the benefit of having neither number be larger than like 6.3, so an underlying/backing type that can offer great precision in this small range would be more efficient numerically than, say, floating points which have insane baggage and gaps

or iunno i'll look into that one a bit later, i'm just kind of furious right now that i rederived stereographic projection on my own when the formulas were right fucking there if id only just googled for them

[map-projection-showdown]

And the winner is...

THE WATERMAN BUTTERFLY!

Congratulations to Waterman's projection for this highly esteemed prize.

In second and third place we have the Stereographic projection and the Peirce Quincuncial.

An interesting top 3 I think, not what I was expecting. We've got a polyhedral compromise, an azimuthal conformal, and a polyhedral conformal. Though I do think this conclusively proves that people prefer projections centred on 20°W rather than on Greenwich.

[phosphophillight]

talk about lenore THIS INSTANT (please)

LENORE!!!! everyone say thank you red … again…

Lenore Caester is the general branch manager of the Verus Technologies Corp, the company behind the Safe Haven Project🙏 She commonly speaks in the royal we. She appears and disappears at the blink of an eye if you’re not actively looking at her. She’s got the kind of voice and diction you’d find in advertisements. (If u wanna get super specific her current voice claim is the fax machine in dhmis s2 ep1.)

In classic VTCO fashion she denies time (the concept).

In one of my first artworks of Lenore ever (the old ones….) she’s holding a pen with a butterfly charm! In my last reference sheet of Lenore it only has one wing. The full butterfly is usually used to symbolize the actual CEO, while the single wing is for SUGAR (the CEO).

Lenore “adopts” Axl after the finale of genesis part 2. Axl runs into Lenore in the elevator and shes like “Hey You wanna go to school?” n hes like. omg yay. school⁉️⁉️⁉️

Lenore is like an android of sorts! She’s either a dead woman put back together or simply based on a woman previously alive. She either doesn’t remember or simply no longer feels attached to anything regarding her “past life” or “identity”. To stay true to her detachment from her past I likely won’t write her origins/mention it.

She’s shown to possess a lot of admiration for the actual CEO and speaks very highly of her.

Lenore isn’t super fond of most of the characters around her relevance level in the story. Main one being Edgar Reynaud! Obv. She doesn’t like him much. She also has a negative relationship with Azimuth! Azimuth has more of an upper hand there as their source of tension is Az’s unwillingness to cooperate. This leads to her getting dragged to mundane activities and hangouts with Az that she has to sit through in the hopes that he comes around eventually. Neither Lenore or Az are open about it when they dislike someone! So while they r both aware that the other person doesn’t like them either, from a 3rd person view they have a fun dynamic i think ^_^ Lenore is generally passive aggressive in a very artificially warm corporate way, while Az likes to fashion his distaste as something more flattering… so hes VERY nice. Hes very nice about it ^_^

Lenore’s dynamic with Morgaine is also interesting to me! It’s quite common for Morgaine to be the person getting the short end of the stick. I feel like she’s always the character who simply doesn’t know background information characters around her know. I feel like it’s a very cruel way to put it but she does end up being the laughingstock very frequently… n it’s not really her fault that this happens. This kind of continues with Lenore. Lenore is her boss. But also not really, because she never actually signs a contract to work with the company. There’s stuff Morgaine confines in Lenore, simply because she has to talk to SOMEBODY and theres not a lot of options. Ok apologies for the morgaine rant i love morgaine can u tell shes one of my favorite characters lmao . She’s still an outsider in the new world that’s been established. For many reasons. It’s kind of when you learn how a magic trick works and it just ruins the magic for you. She was there when a good chunk of the new world was being built, and she knows enough of it is false to be able to ignore it and live a “normal” life. Her normalcy isn’t whatever this is. Therefore she has to confine in people who are also outside this “normalcy”. Lenore is a good candidate for this very reason. For Morgaine, Lenore is the closest thing she can get to talking with a real person who’s also not going to invalidate every second thing she says. Lenore is semi-aware of this. She’s also aware of how horrified Morgaine was to learn the guy she thought she murdered was actually a robot. N there’s a little humor in it for Lenore. Because she’s also a robot.

On a less lore related note, I initially designed Lenore based on a random oc generator prompt thing i got from a website bc I was bored 🤧

Lenore also briefly shows up in a prequel story titled UO! She accompanies Una Hearthelow (creator of The quantum computer / edgar) to a vcto owned skyscraper.

If you remember The Umbrella ™ cycle, Lenore holds an umbrella over Morgaine at the finale of World’s End.

More character design details wise… She’s blue! Obviously because she’s a textbook #BC (aspect type). But she also has some pinks. Who are the pinks associated with? The CEO!!!!! Yippeee!!!! She also has very organic shapes throughout her design, with her dress somewhat resembling waves or water. These are also stuff associated with the actual CEO. She does have my statement square/rectangle shaped irises I give most of my robot-ai-any sorta techy characters! (It’s mostly a stylistic choice, her eyes likely just look. “normal” to everyone else) Her pupils are the 2 triangle hourglass-like shape that’s the vtco logo! Her eyes are a more purple color, i think mainly bc i just like it that way. But u could read into it with knowledge of what purple is associated with in my character designs/worldbuilding.

I’ll call it a day for now…. Feel free to ask me more specific details like dynamics with other characters yada yada.. either here or on discord 🫡

WIP Folder Game

ty so much to @enigmatist17 for the tag!

RULES: post the names of all the files in your WIP folder, regardless of how non-descriptive or ridiculous. Let people send you an ask with the title that most intrigues them, and then post a little snippet or tell them something about it! and then tag as many people as you have WIPs.

So I use Scrivener projects, which means I don't have individual docs for a lot of things but projects which in turn hold a bunch of stuff. That said, the WIP folder has the following Scrivener projects:

Descent_timeline - Descent actually has a potential interquel and sequel, Azimuth and Declination, but I don't know if I'll write them. I'm undecided, I had a couple of scenes for each. Declination was Cross and Omega in Tantiss and Azimuth was Phee's POV of Descent. I may still do Azimuth, but Declination feels a little redundant now.

Obliquity_timeline - Obliquity's sequel, tentatively called Precession, is about 15-20% done but fully mapped/planned, and I hope to get it done once MSS is finished.

Downside_timeline - Down Side of Me has an interquel, from Phee's perspective, which I will probably still write but I only got about 20% through before Obliquity ate me alive.

TBB_ficlets - This is the catchall bucket for smaller projects, which contains…

Westpunk AU - This one probably won't get written, but maybe it will as a little one off (she said, like she did for MSS, and well, anyways...). The idea was a sort of Western setting variant similar to MSS but in the way MSS is early 1800s-ish tech with biopunk and alchemy, this would be late-1800s western, with airships and solarpunk and so on. Phee is from a small island off the coast in need of trade with the Tuskens, and the Batch have some interactions with them and can offer passage and a trade liason. There are bandits. There are flying fathiers. Etc.

Starfall - This is a potential little oneshot adventure, Tech and Phee spelunking in a ruin. I'll get to it at some point. Mapped out, not written.

Crack - This is a truly ludicrous modern AU @ahsokastechie and I came up with to satify our ridiculous desires for a situation in which Phee and Tech are Magic: the Gathering nemeses. It is truly ridiculous and has no redeeming qualities, and I love it.

MSS_timeline - Mercury Salt Sulphur has a putative followup, called Axis Mundi, but I'm still thinking it over. It would be kinda fraught. But maybe that's okay. We'll see.

Prawns - This is, you know. The porn collection. Of which there's not much, but there it is! The only WIP in it at the moment is for MSS, called Quintessence.

I NPT all the people! Especially @nightskyfoxyy and @ahsokastechie! But anyone who sees this, REVEAL TO US YOUR SECRETS. You know, if you want to.

[samuraisharkie]

had an utter brain blast moment last night bc I was revisiting my troubling and deranged special interest in Ratchet and Clank and how Alister Azimuth fits all the categories of Sad Troubled Old Man that tumblr loves but the problem is that he’s a fictional furry creature which ruins everything but THEN I thought. I could make him some guy. My new pet project is to trick everyone into adopting a new Old Man by giving Alister Azimuth a human design and not telling anyone where he’s from until more than one person has been compelled by him. I will then force them to suffer my fate of knowing what he truly is and all the shame that comes with it

[patricia-taxxon]

🌂 Is there a name for taking the inside 1/2 of the radius (so quarter of the area) of one azimuthal projection (centered on say, the north pole) and then doing the same with an projection centered on the opposite point on earth's surface (say, the south pole) and presenting the two side by side, as that would cover all the surface area of earth? also you could then stick them on opposite sides of a coin, ehehe. I imagine this has loooooads of problems for the equator (or whatever band is maximally distant from alternate chosen points) but it'd be like, strictly better than the azimuthal for most purposes, right? the only problem (in comparison) is the headache of jumping from one map to the other, but clever perimeter markings (0°, 20° 40°, etc or whatever would work) would help with that, right?

yes!

[dawn-of-worlds]

Various Absences

In which the Lunar Bridge is made permanent and a strange bureaucratic process forms in the courts of the Moon.

False-Fires infiltrate the Págar Star-Counters, creating the mysterious Society of the Flickering Stars.

The cities of the Occident grow supernaturally tall and proud.

And a refugee founds Gingat, the only honest city in the world.

Corobel starts turn 16 (I know, I know) with 14 points: 8 (roll) + 3 (nonhoarding) + 3 (left over)

Event (-9): The sages of Ecliptic have long (by the standards of that young society) sought to reopen a permanent connection between the two worlds. Azimuth, too, desires reunion with its lost children.

It is the Págar Moon-Watchers who first suggest a system for sending signals between the two worlds; on one fortuitous eclipse, they float through the red wound with a code, a map, and some of their finest telescopes. The project will require the connivance of both ends of the equation; knowledge is shared, efforts coordinated. Eventually, a solution is found, though none now remember it. It involves an expedition to the lake-bottom, conducted by Night-Singers, and another to the core of the Moon. They do not learn the secret, but they get quite close, close enough that the self-sealing

For one awful moment, the world is clear glass; they see the Tree for what it really is; they see the present from the outside, and cannot find it. Their minds blank and revolt, and their eyes are struck the pure black of the moon in eclipse.

The bridge-pieces are forced into a permanent alignment, eclipses being no longer required; the contents of the lakes no longer switch places; but all who immerse themselves in a certain part of the lake find themselves transported.

Relics of the experiment (lenses, scalpels, mirrors, lamps) resist being understood or remembered, and may (or may not) have certain other supernatural properties, which are (necessarily) rather nebulous.

Command Avatar (-1): Meanwhile, as the gracile bureaucracy of the Court of the Two skies swells with the tithes of the algal fields, the Coryphaeus makes it known that the Moon needs something. A system is established; applicants are received, vetted, reviewed, processed. The pale-vaulted chambers throng. Something is taken from them, though nobody can say quite what. No change can be discerned, but payment is received, in the eerie jewels of the Moon’s heart.

Command Avatar to Create Order (-1): Some Págar Star-Counters are taken in by False-Fires, creating the Society of the Flickering Stars.

Command Avatar to Command Civilization(-1): The cities of the Occident begin a campaign of monumental architecture, enhanced by magical techniques. Towers and ziggurats, sponsored by the great clans and religious associations, reach impossible heights.

Command Avatar to Found City (-1): There was a city in the Occident which was governed unsurpassedly well, whose streets were clean and friendly, whose councillors, in clean pressed linen robes, ruled a peaceful and a quiet people. Its constitution was engraved in white travertine for all to read, and the laws it gave were respected universally. Travellers came to see them from the very vertices of the earth. In that fine republic, all knew their place, and all knew their place was just.

I will not name that city. I will not elaborate the laws that structured the perfection of its life. They are no longer important. You know why. What else could happen to such a place?

There was one survivor. As he shuffled away from the ashes, tasting salt, the old city fell from his sandals and his mind, and a secret coagulated in the locket around his neck—or did he carry it from the ruins? No matter.

He would make a new city, and he would do it right. It would be the only honest city in the world.

Whosoever could kill him in open combat would become the king, and pluck the terrible secret from the phylactery of his neck, and open it, and not reveal it, and be killed in turn.

Across the sea, in the lands where the seasons change, he founded Gingat, the Honest City.

🎫 Azimuth

In the early years of the war, he tended to stick around the Wreckers and help them with minor issues, but never saw himself as one of them for many reasons. They were too rowdy, too unorganized for his liking and his rather snobbish, cold personality which only got worse after his brother's death did not suit most of the Wreckers.

However, to everyone's surprise, he got along with Wheeljack just fine. The inventor and bomb specialist was glad to have a smart mech he could rely on for calculations. They developed a friendly rivalry - Wheeljack showed him how to create explosives and Azimuth taught him complex mathematics he needed for his projects in return.

They even share similar paintjobs (white, green and red) but purely by accident. Azimuth's paint was color-picked from my best friend's travel kit because they were so nice and I turned them into a Transformer (white, green, red, black, purple, pink, blue). That's how he was made.

His brother Altitude has a similar color scheme (white, green, red, black, orange, pink). Instead of light blue and purple, he wears orange. Even though they're twins, they don't look alike much. They share faceplates, an alt mode and a passion for theatre, but that's it.

Astrolabes Front: An Overview

Ring: Used to suspend the astrolabe for star readings (typically hung from the thumb)

Throne: top of astrolabe to hold the astrolabe body and ring in place

Mater: The astrolabe body (from Latin word for “mother”) which holds all the tympans (plates) within itself

Tympan: An inner plate engraved with one or more projections of the sky for particular latitudes and quadrants of unequal hours

Stereographic Projection of Local Coordinates: Arcs of altitude and azimuth for a particular latitude engraved on the tympan. They form a grid on which to locate stars

Unequal Hours: Used to find the time using a system of seasonal, unequal hours that divide every day and night into twelve hours

Equal Hours: The raised rim of the mater is divided into degrees and 24 equal hours (like that used in our modern timekeeping system)

Rete: Named from the Latin word for “net,” this pierced disk is a map of the sky. It is a stereographic projection of the great celestial circles and stars onto the plane of the Celestial Equator as seen by one looking up at it from the South Pole

Star Pointer: The tip of a star pointer indicates the position of a bright star on the map

Rule: An index for lining up points on the ecliptic and outer scales on the mater in order to read the astrolabe

Ecliptic: The offset circle is the ecliptic, the path of the Sun and planets through the 12 signs of the Zodiac

Horse: Holds the plates within the outer “mater” format
