Spatium anni vertentis id esse, periti mundani motus et siderum definiunt veteres, inter quos Meton et Euctemon et Hipparchus et Archimedes excellunt, cum sol perenni rerum sublimium lege, polo percurso signifero, quem  sermo Graecus appellat, trecentis et sexaginta quinque diebus emensis et noctibus, ad eundem redierit cardinem, ut (verbo tenus) si a secunda particula elatus Arietis, ad eam dimensione redierit terminata.
The extent of the revolving year is completed, according to the calculations of men of old who were versed in the movements of the universe and the stars, of whom the most eminent are Meton, Euctemon, Hipparchus, and Archimedes, when the sun, in accordance with the eternal law of the heavenly bodies, has traversed the signs of the heaven which in Greek are called , the zodiac, and after the course of 365 days and nights returns to the same turning-point; that is (for instance) when it has started from the second degree of the Ram and after completing its course has returned to the same place.
