Triquetrum/FAQ
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 asked a Latin teacher for the proper pronunciation, who stated that the correct Latin translation is the same as the second English option in this video: tri-QUET-rum, not tri-QUEET-rum
