The Achilles Mosaic was at the bottom of a pool with a waterspout in the impluvium of the Poseidon Villa in Zeugma.

Achilles has been sent by his parents to a friend-King's palace where he even dresses up as a woman. Odysseus wants to find him, an plays a trick to find him amongst the "women": he brings fine gifts of clothing, jewellery, but also fine weaponry. The one to grab that must be Achilles. Here he's found out.
