The main street itself was in many parts filled completely, and around the naumachia Augusta great heaps were piled up.
In a naumachia given by Nero, there were sea-monsters swimming about in the artificial lake.
After the naumachia, the moon rose, and the Chinese lanterns were lighted.
Sometimes the vast arena was flooded with water, and naumachia or sea-fights were exhibited.
Another form of the spectacle for the entertainment of the Roman public was the naumachia, or naval battle.
