On this date in 585 BCE, a total solar eclipse caused a break in the war between the Lydians and the Medes, leading to a truce. The eclipse was particularly noteworthy because it had been predicted by Thales, the man of Miletus who became known as the world's first philosopher. Since the eclipse was recorded in various histories, this event is one of the cardinal dates from which other dates are calculated. See this link for more information about the origin of BC/AD dating (now using the letters BCE/CE). My tie features sunbursts and various calendar cycles.
