Summary
Hypsicles of Alexandria was a Greek mathematician and astronomer who flourished around 190 bce. Two of his works are known to us: the first sets out a linear arithmetical scheme for computing the rising times of zodiacal signs (ascensions) and the second is a continuation of Euclid’s Elements which became known as Book XIV. The latter work contains a detailed study, in eight propositions and various lemmas, of the comparison between a dodecahedron and an icosahedron inscribed in the same sphere. This work was close to Euclid’s work in style and format and, because of this, became a part of the textual tradition of the Elements.
