Romulus, the son of Maxentius, died in 309 A.D. All his coins were issued after his death. The ruins of Romulus' tomb, sometimes erroneously called the stables of the Circus of Caracalla, are located in a large enclosure forming part of the villa of Maxentius on the Appian way, about one mile from the gate of St. Sebastian. The Temple of Divus Romulus on the Via Sacra, and adjoining the Basilica Maxentius, was unfinished at the time of the usurper Maxentius' downfall in 312 A.D. and was completed under Constantine. The temple presumably was dedicated to the founder of the city rather than to Maxentius' son. It is not entirely certain which of these two similar structures, the temple or the tomb, or both, are depicted on Romulus' coins. David Sear believes images with columns depict the temple and images without columns, depict his tomb.
