The BBC have unveiled the first promo pic for Atlantis, the new 13-episode drama series from the writers of Merlin.

The city of Atlantis is a mysterious, ancient place; a world of bull leaping, of snake haired goddesses and of palaces so vast it was said they were built by giants. It’s into this strange, compelling realm that the young Jason arrives and an amazing adventure begins, bringing to life the vast store of Greek myths and legends re-imagined for a new generation.

Featured in the image from left to right are Pythagoras (Robert Emms), Jason (Jack Donnelly), Hercules (Mark Addy)

Atlantis airs this Autumn on BBC One.
