I'd hesitate to call Tyrian Purple even a distant cousin of Phthalo dyes. They are both dyes and that is about the only connection. Phthalos are synthetic dyes, Phthalo Blue was first produced in the 1920s and commercialized in the 30s. Phthalo Green is made from Phthalo Blue, not sure when it came about, but clearly after the blue. Both are phthalocyanine compounds with copper.
Tyrian Purple is a naturally originating dye from "Murex" snails (a few different species, none are actually genus Murex anymore), and it has been used for thousands of years. The main color compound is an organobromine called 6,6'-Dibromoindigo, it is related to indigo dye.

Akan weights in the form of mudfish
Ghana / Côte d'Ivoire, 18-19th c.
Copper alloy
On display at National Museum of African Art, Smithsonian Institution
Symbols of: wealth, power, transformation, resilience
Copper alloy
“Visually, [Akan] weights fall into two distinct categories: geometric and figurative. Stylistically they are divided into early (c. 1400-1700) and late (c. 1700-1900) periods. During the late period, figurative weights increased in both number and variety, although geometric weights were still made. Generally, late-period figurative weights have added details and textures beyond the basic form that would identify the subject.”
“Some weights’ forms were selected just for their beauty or to display the owner’s status. Many, however, evoke Akan proverbs, whose meanings vary with time and place—more than one interpretation can apply. Hence water creatures were popular weights, with their associations of fluidity, flexibility, and movement between worlds.”
“Th[ese] weight[s] [are] in the form of mudfish, a symbol of wealth and transformation. The mudfish lives when ordinary animals would die, surviving the loss of water.”

I messed up the hot glue a little bit but I'm sure my mistake will eventually be lost to time.
