COSMOGRAPHIAE

The Sun, therefore, to return to where we digressed, completes his journey in the Zodiac in the space of a year, that is, in 365 days and 6 hours; and when he enters the sign of Aries, he brings forth the beginning of spring under the Equator itself.

But passing through Taurus and Gemini, he at length approaches the point which is the vertex of our head, until he reaches Cancer, the part where the summer Tropic passes; then, having become closer to us, he brings more fervent heat and longer days. We will discuss these things, however, when we have reached the description of the Horizon.

Furthermore, progressing from Cancer through Leo and Virgo, he migrates into Libra, which sign corresponds to Aries on the other side, in the circle of the Equator.

For it has been discovered by the diligence and long practice of astronomers that the degrees of revolutions
