Temple of Venus, Baiae
About
The folk name is a myth: this octagonal domed hall was a heated bathing room in a bath-and-villa complex, named for a statue of Venus found in its rubble. Excavators date the structure to Hadrian's reign, its dome ranked among antiquity's largest after the Pantheon and Diana's hall nearby. Bathers moved through its warm chamber toward the shore-facing baths over the bay. Built under Hadrian, this hall postdates Trajan's death and did not exist at this map's 117 CE snapshot.
What happened here
The furnaces are lit before dawn and the water is hot by the eighth hour, which is when the town arrives. The circuit is a habit: undress and hand your clothes to an attendant who may or may not be watching them, exercise in the courtyard, sweat in the hot room, scrape the oil and dirt off with a curved bronze strigil, then the warm pool and the cold plunge. Entry costs a coin small enough that almost nobody is priced out, and on a benefactor's birthday it is free. There is food, drink, ball games, gambling, hair-plucking, business and shouting; a writer complaining about the noise from the flat above is complaining about all of it. Men and women bathe at different hours, or in separate wings.
