Mercury (Hermes) and Virgo

I think this is a cool picture. It was in a poster for Universidad de Salamanca back in the 80s and one was given to me.

During a move I threw it out (stupid), figuring I’d be able to view it on the web. But repeated web searches haven’t found it.

So… does anyone know the origin of this artwork?

It looks like an old Roman wall or ceiling painting to me.

I’d like to track it down, and hopefully look at some high-res zooms on the web.

Let me know, if you know…
