A sick child brought into the Temple of Asclepieion, by Waterhouse (1877)

Year 300 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Corvus and Pansa (or, less frequently, year 454 Ab urbe condita). The denomination 300 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. B.C.E is the abbreviation for before the Common/Current/Christian Era (an alternative to Before Christ, abbreviated BC).
