Temple of Jupiter Feretrius

"Jupiter Feretrius," he said, "to thee I... dedicate a sacred precinct… to be a seat for the spoils of honour which men shall bear hither in time to come, following my example, when they have slain kings and commanders of the enemy."

[5] A visual representation survives on coins minted by Lentulus Marcellinus, a nobleman whose ancestor Marcellus had made a famous offering to the temple.

[2] As per the passage in Livy, Romulus placed the armor of the slain Acro in the temple, inaugurating the tradition of spolia opima being dedicated to Jupiter Feretrius.

[7] Alongside these trophies the temple held a sacred piece of flint and a scepter, ancient relics used by the Fetials in the ceremonies attending the signing of treaties and the declaration of wars.

Augustus, not intending that an ambitious nobleman should receive this rare honor, declared that nobody with a rank less than Roman consul was eligible to offer the spolia to Jupiter Feretrius.
