Hey, this is greek mythology. Libra isn't in it. Also, Hades is the god of the dead, Thanatos is his lieutenant. Also, Thanatos is a guy, soooo...not sure about that in this picture.
There maybe some confuse here, I guess. Since Thanatos, is more like a judge for those who died so maybe cover his eyes in order to let him have a fair judgment on every souls. And Libra also in the same case I think.
Yes, but Libra isn't in Greek or Roman mythology, thus being completely unrelated to the picture, or the whole thing at all. This is Greek mythology, not the zodiac. Get it right.
