Не вступая в дискуссию, советую начать смотреть с этого места:
Pliny the Elder, The Natural History. Book XVIII.
CHAP. 59.--THE EPOCHS OF THE SEASONS.
... The winter solstice begins at the eighth degree of Capricorn, the eighth day before the calends of January, in general; the vernal equinox at the eighth degree of Aries; the summer solstice, at the eighth degree of Cancer; and the autumnal equinox at the eighth degree of Libra: and it is rarely that these days do not respectively give some indication of a change in the weather.
These four seasons again, are subdivided, each of them, into two equal parts. Thus, for instance, between the summer solstice and the autumnal equinox, the setting of the Lyre, on the forty-sixth day, indicates the beginning of autumn; between the autumnal equinox and the winter solstice, the morning setting of the Vergiliae, on the forty-fourth day, denotes the beginning of winter; between the winter solstice and the vernal equinox, the prevalence of the west winds on the forty-fifth day, denotes the commencement of spring; and between the vernal equinox and the summer solstice, the morning rising of the Vergiliae, on the forty-eighth day, announces the commencement of summer. We shall here make seed-time, or in other words, the morning setting of the Vergiliae our starting-point; and shall not interrupt the thread of our explanation by making any mention of the minor constellations, as such a course would only augment the difficulties that already exist. It is much about this period that the stormy constellation of Orion departs, after traversing a large portion of the heavens.
The vernal equinox appears to end on the eighth day before the calends of April... (Chap. 66.)
We have already stated that the summer solstice arrives at the eighth degree of Cancer, and upon the eighth day before the calends of July: this is an important crisis in the year... (Chap. 68.)
... On the eleventh before the calends of October, the point of junction in Pisces disappears, and upon the eighth is the autumnal equinox... (Chap. 74.)
