Roman legions no doubt had funeral rites for fallen comrades. Suspect they involved a lamp and a bronze coin for the dead soldier’s safe passage to the Elysian fields.
Could also be a previously unknown board game, a sort of reverse D&D — instead of a bunch of college-aged couch potatoes imagining themselves involved in archaic warfare, a bunch of men involved in archaic warfare were imagining themselves doing something else.
And it might have been 22 legionaires were killed in a battle in which the Legion lost thus unable to recover and properly bury their dead. The funeral service held back at the Roman permanent camp : alamp to light the way and a coin for the ferryman for each soldier.
