Ok, this is a very specific and potentially pointless question, but my curiosity was aroused and I can't find any relevant information to quench it.

I live in Birmingham (Alabama, not England), and Vulcan is a pretty prominent symbol here. Recently there was a Vulcan-related function, the invitation to which used this picture of a relief of Vulcan. I know someone who works with the person who included that picture on the invitation, and the only information I could get concerning the picture was the url to the photobucket page they drew from. The description there was "Marble relief of the god Vulcan at Herculaneum Italy." I then did some google searching and came upon several results of the same picture, where the words "The chapel of the four gods" kept popping up. Google searches for this chapel have come up dry and I could not find any reference to it in articles on Herculaneum.

So: Do any of you have any knowledge of this relief or The Chapel of the Four Gods? Does that chapel exist? Is this relief done Roman-style art? (To my very untrained eyes, it looks like the way Egyptian art represented humans, e.g. the way the feet look, the not-so-3-dimensional feel, etc.)

Thanks for any and all help y'all have!
