#### Per Gorchestopher's comment, the above image is a deviantart (i.e. fanmade) picture by [Stephen Howard][1] showing a "Celtic Supergirl", part of a series of 73 "[out of time][2]" images suggested by fans.

On the subject of Superheroes in Ancient Rome, there *have* been some time-travel stories you may be interested in including "Lois Lane, Slave Girl!" (from [Superman's Girlfriend Vol 1, #33][3]). Lois is transported in time and sold as a slave.

![Lois Lane, Slave Girl][4]

["Challenge of the Superfriends - The Time Trap"][5] in which Superman, Batman and Robin are transported to Ancient Rome to face fearsome lions (well, one arthritic-looking lion at any rate) in Caesar's gladiatorial arena.

![Challenge of the Superfriends][6]

And "[World's Finest #198][7]" in which a pyjama-clad Jimmy Olsen is sent back in time by Superman and the Flash's speed challenge. He faces a Centurion who (unsurprisingly) decides to kill him.
