Warship Bow and Fire pot

 

Warship (note the sharp ram to the right in the picture) equipped with a fire pot. This was a graffiti (Graffito) in an Alexandrian Tomb; after A Schiff, "Alexandrinische Dipinti," (Liepzig -- 1905) pl. 1. The fire pot probably refers to the use of "Greek Fire" which was a very inflammable liquid used against enemy ships. It was very successful as an offensive weapon.
