"eat by their lights"?

Posted by Word Camel on March 13, 2005

This is a synopys for an article that translates ancient roman recipes. I can't work out, for the life of me what it means. The recipes are for everything from greens to roasted tuna. And they look fine to me. There's nothing odd about them. I think I just must not know the expression.

"Ancient Romans knew how to eat, uh, by their lights anyway. Whether they match your lights is for you to decide..."

Thanks in advance,
