Talk:Timeline for the Masks of Dii Consentes
B.C. timelines are always a countdown to year 1 B.C., so Phidias could not have done something in 339 in preparation for 340 - the previous year. After 1 B.C. medieval calendars and our own began with year 1 A.D. and ascend thereafter. There never was a year zero. And the B.C./A.D. calendar was not used until around 1200 A.D. -- "The Magister 14:53, 19 July 2020 (MDT)"
