From a Roman bathouse there is a series of mosaics, inventory numbers 825, 829 and 830. They represent sea-related scenes. They are on one floor in the new museum, but I here sort the ones with number 829.

In the catalogue it is indicated that they are all from the same room in an Antakya bath house, fourth century AD. I used to have the other mosaics from that bathhouse in a set with these, but decided to order them with the mosaics in general.

From the Wikipedia I understand that a group of followers of a god, often in their ecstacy, was called a thiasos. Most often we see the one of Dionysus, but this must be one of the sea god Poseidon, depicted as a triumphal wedding procession with Amphitrite, attended by figures such as sea nymphs and hippocamps.

This pareticular scene seems to be "Nereid Kymodoke Rides Triton Agreus and Triton Palemon with Nereid Aktaia".
