No, all the materials to make a cannon were not known during the Bronze Age. The Bronze Age happened from about 3300 BC to 300 BC. Cannons require a fuse, gunpowder, and iron or other material to house the chemicals. Gunpowder was discovered around the 9th century AD. So all the materials to make a cannon were not known during the Bronze Age.
