13 September – On this day

The first building of the temple of Jupiter was dedicated on this day 509 BC Marcus Horatius Pulvillus (one of the consuls) was chosen by lot to perform the dedication.

The original temple is thought to have measured 60m x 60m and was sacred to Jupiter, Juno and Minerva. Each deity was given their own cella within the temple.
