Did the colosseum have canvas awnings?

Yes, the Colosseum did have canvas awnings. These awnings were called the velarium, and they were used to protect the audience from the sun and rain. The velarium was made up of a series of large sails that were stretched over the Colosseum's roof. The sails were operated by a team of sailors who would raise and lower them as needed.

The velarium was an important part of the Colosseum, and it helped to make the arena a more comfortable place for spectators. It also helped to protect the Colosseum's interior from the elements, which helped to preserve the building for centuries to come.
