The picture depicts a moment in the Voyage to the Divine Union Feast – Hathor’s 106 mile journey from Dendera to the temple of Horus at Edfu, which she did each year to visit her husband Horus at the feast of the Divine Union. Each night the ceremonial barge, carrying the statue of the goddess, would stop off at towns and villages to rest in a barque station (an ancient motel for the gods)
The scene takes place in an unnamed town connected to the Nile by a cannel with its own chapel. Manned by oarsmen, a cannel barge carries the ceremonial barque containing the enclosed statue of the goddess. The high priestess from the temple of Hathor and her entourage, some of whom are singing and playing musical instruments, are among the passengers.
On the dock-side are the local officials and their families who are there to greet the goddess. In the foreground, between the two obelisks, stands an old priest, and next to him is a large man who is likely the local mayor/headman. Behind them stand a line of young men, they are the litter bearers who will carry the sacred barque from the barge to the barque chapel.
To the right, on the dock steps are two boys – their heads are shaved and they wear the side lock of youth. I don’t think they are interested in the event and are focused on playing in the water.
