Oh, it gets better. The camel/hide shirt is in the majority of icons, (sometimes just draped over a shoulder as his only clothing, woo-hoo) but even when John the Baptist is more formally dressed, his hair is always "unkempt".

I won't even get into all the times he's shown with wings (symbolizing his prophethood), and/or holding his own decapitated head. In addition to having a head on his shoulders, of course, not instead of.

Maybe John the Baptist icons need their own post. There's even one of the baby Baptist with his mother St. Elizabeth. He's wearing a little baby shaggy hide tunic, naturlich.
