Council of Palestine under Pope Victor defined that the world was created at the vernal equinox, that the first day of the world was March 25, and that Christ was incarnated on March 25
"Third, because the Council of Palestine, held under Pope Victor in the year of Christ 198, defined this very thing. This Council proves its opinion from the word \"let it germinate\": for in spring the earth begins to germinate. It also teaches that the world was created at the vernal equinox, proved from the fact that God then divided light from darkness into equal parts, which occurs at the equinox. It adds that the first day of the world was March 25, on which also the Blessed Virgin received the Annunciation, and Christ was incarnated in her, and on which after 34 years He either suffered or rose from death. It is certain that this day was a Sunday."
