The SVG for the Gorgona was derived from that for the Medusa, and apparently it inherited the characteristic that prevents its rendering by fen2.php.
For what it's worth, showpiece.php produced PNGs for both of these when I ran it on the SVGs a few days ago. However, pieces with these names should show a woman with snakes for hair rather than a target with lines or arrows coming from it, which seems to be based on how a particular piece moves instead of its name.
