2From the breast of Leo and the boundaries of Cancer, the sun moving through the other parts of Leo, has by that time diminished the length of the day, as well as of his circuit, and resumes the equal motion he had when in Gemini. Hence from Leo passing to Virgo and proceeding to the indented part of her garment, he contracts his circuit, which is now equal to that which it had in Taurus. Proceeding then from Virgo through the indentation which includes the beginning of Libra, in the eighth part of that sign, the autumnal equinox is completed; the circuit being then equal to that in the sign Aries.
2After leaving the breast of Leo and the boundaries of Cancer, the sun, traversing the rest of Leo, makes the days shorter, diminishing the size of his circuit, and returning to the same course that he had in Gemini. Next, crossing from Leo into Virgo, and advancing as far as the bosom of her garment, he still further shortens his circuit, making his course equal to what it was in Taurus. Advancing from Virgo by way of the bosom of her garment, which forms the first part of Libra, he determines the autumn equinox at the end of one eighth of Libra. Here his course is equal to what his circuit was in the sign Aries.
