Frequently Asked Questions for the Eclipse Triquetrum project.
General
What is a triquetrum, anyway?
"The triquetrum (derived from the Latin tri- ["three"] and quetrum ["cornered"]) was the medieval name for an ancient astronomical instrument first described by Ptolemy (c. 90–c. 168) in the Almagest (V. 12)" (Source: Wikipedia)
Pictured is the triquetrum of Copernicus from Meyers Großes Konversations-Lexikon 6. Auflage 1905–1909.
The Eclipse Triquetrum project uses Ptolemy II as its execution engine and the Ptolemy II icon shows Ptolemy holding a triquetrum. The name also evokes the model-view-controller pattern.
How is triquetrum pronounced?
We are working on that.
