Adonis the hoplite Picture

Adonis of Corinth, an original character.

I bet you're wondering about the shield, right? Well it's the penis of Priapus, protector of livestock, fruit plants, gardens and male genitalia. That's right. Protector of male genitalia. Well, I'm sure someone somewhere in the ancient world put a dick on their shield for their personal insignia.

It's also a symbol of Greek manliness. ARRRR.

EDIT: Looks like I found a more appropriate god! See if you can spot the change I made from the original.
