ROME'S GREAT TEMPLE OF JUPITER DEDICATED ON THIS DAY IN 509 BC

ON the 13th of September the Temple of Jupiter Optimus Maximus atop the Capitoline Hill was dedicated in 509 BC. The ascent of Rome began! 

In the old Roman calendar, September was the seventh month of the year in counting March as the first. Among the festivals observed in September were several honoring Jupiter. 

He was hailed as the chief of the gods and had many epithets as a result.

As Jupiter Optimus Maximus, he occupied the temple of Jupiter Capitolinus on the Capitoline hill with the goddesses Juno and Minerva. With them, he received a Lectisternium (September 13) and the Ludi Romani  (September 5-19).
