Caption: Two Druids in an 1719 engraving that was copied from a bas-relief found at Autun, France.
This an imaginative portrait of Druids---nevertheless maybe it's NOT so far from the truth, mutatis mutandis.
Perhaps they are debating whether or NOT to insert an intercalary month in their lunisolar calendar---if the Celts had that---the one on the left is holding a crescent moon---or is it a banana:
