Description
Sundial with armillae (rings). The Sun's ray shows the time when it passes through a hole bored in one of the rings and strikes the opposite inner face of that ring, which carries the set of hour lines. The armillae indicate the main circles of the celestial sphere: meridian, equator, and solstitial colure. If it carries the shadow scale, the ring dial can also be used to measure distances. The variety of its functions is illustrated in the collection of writings by several authors (including Regiomontanus, Reiner Gemma Frisius, and Oronce Finé) printed in Paris by Gulielmum Cavellat in 1557 under the title Annuli astronomici... usus.
