![TROLLIUM (Menstrual Chart) | circa 1966-71 | Photo by Ann Cady, 2024 | ©2026 Norman Daly Art: The photo shows a weathered and corroded paper-like fragment, rectangular in shape, with a rough, textured surface. It appears aged and deteriorated, with signs of wear and decay that give it a historical or archaeological feel. Embedded within are two prominent geometric features: the top one contains a set of small, raised dots in a rectangular outline, while the bottom features an outlined shape resembling an upward-facing triangle.

[1972 Exhibition Catalog] The pegs and dials of the trollium were adjusted by lunar reference and were used to indicate fertile periods.
The ultimate decline of the people of Llhuros was not the result of inter-nascent discord or foreign invasion. It was the direct consequence of their stupefying apathy and, according to most anthropologists, the infallibility of the trollia (see catalog narrative page 14).](https://d8e7jbdw4fu0e.cloudfront.net/13541/3809dde0-73aa-11ef-bc5a-af20456466e2-wx3P1rl.lg-nt@2x.jpg)
