I was flipping through a David Ligare book about a month ago. His stuff is alright. I wouldn't say it's great though. It's sort of got the right idea, but he didn't develop the idea far enough. He stopped at 50% when he could have been truly great if he'd just kept going the way he started. Nevertheless, I did like two of his paintings: Archer in a Landscape, and one called something like Achilles and Patroclus.
I'm seeing a bit of the Ancient Greek in those pictures the thread starter posted but I'm also seeing some Art Nouveau and Art Deco style. Either way, here's some stuff that might match.
I think this was an NC Wyeth picture depicting Odysseus.
This is by Jean Dupas.
