Note 107 — THE WORKS AND DAYS.

The wintry tropic.] The winter solstice, according to the table of Petavius, happened in Hesiod’s time on the 30th of December. The acronychal rising of Arcturus took place in the 14th degree of Pisces, which corresponds in the calendar with the 5th of March. Le Clerc.

The acronychal rising of a star is when it rises at the beginning of night: the acronychal setting is when it sets at the end of night. But there are two acronychal risings and settings: the one when the star rises exactly as the sun sets, and sets exactly as the sun rises. This is the true acronychal rising and setting, but it is invisible by reason of the day-light. The other is the visible or apparent acronychal rising and setting; which is, when the star is actually seen in the horizon.
