part of a wrought iron frame, British museum, Bloomsbury, London, England

these oxhead terminals form part of an iron fire frame or fire-dog which dates from circa  50 BCE - 25 BCE

it was found in a rich cremation burial at Welwyn, with silver cups and five wine amphora, its function is unknown - the frame may have been used to spit-roast meat, like a fire-dog but traces of wood preserved in the corrosion may indicate that it was a sacrificial table or altar
