Roman siege towers during sieges were sometimes protected from fire using 'vineae'. Which mechanism minimized flammability?

💡 Explanation

The layered vineae construction created small air gaps through convective cooling that dissipated heat transferred from fire projectiles, which prevented the primary wooden structure from reaching ignition temperature. Therefore, vine layering was applied, rather than water systems, chemical retardants, or specialized mineral insulation which require advanced technologies to implement.
