Isis Clothing

What is the Roman Isis wore on his head? I know that an Egyptian sun between two cow horns, but I can not find information on the clothing of the Roman version of Isis.

There is no "version" of the habit of Roman Isis. Different representations show him different things. Most versions of his show with the head decoration horn-and-one disc that you've described but generally smaller than the Egyptian representations. (See: http://www.ancientsculpturegallery.com/s ... )
Other statues show her with a solar disc and plumes (see: http://www.forumancientcoins.com/moonmot ... and http://image60.webshots.com/160/8/80/31/. .. )

I'd look for more examples, but I think my computer downloaded a virus while I was checking images - in any case, I hope you began.

Roman Isis was the Egyptian Aset, Isis wear a symbol of a throne on her head shape, means power.

Isis is the feminine archetype for creation - the goddess of fertility and motherhood. Its name literally means women throne, ie Queen of the throne. Her original headdress was an empty throne chair belonging to her murdered husband, Osiris.

haha sky, Latin extra credit?!?!
