- adj. (adj) Pertaining to an Attic festival at the naming of a child; -- so called because the friends of the parents carried the child around the hearth and then named it.
If any shall doubt why at the amphidromical feasts, on the fifth day after the child was born, presents were sent from friends, of polypuses and cuttle fishes?
‘Amphidromical’ comes from a Greek word meaning ‘running about or around.’
