A woman with a chiton (left), and two women with a himation over a chiton (right).
A himation (Ancient Greek: ἱμάτιον) was a type of clothing in ancient Greece. It was usually worn over a chiton, but was made of heavier drape and played the role of a cloak.
The himation was markedly less voluminous than the Roman toga.
When the himation was used alone (without a chiton), and served both as a chiton and as a cloak, it was called an achiton.
The himation continued into the Byzantine era, especially as iconographic dress for Christ and other figures from Biblical times, although it appears still to have been worn in real life, especially by older men of relatively low status.
