Mystery of the greek fire

The Greek Fire is still a big mystery. In the early medieval times, the Byzantine Empire was one of the main powers. It maintained a strong grip over the territories in the Balkans and levant areas. It was also treated as a powerhouse of seas. It had a big fleet and was said to have used a flamethrower on their ships. The reports said that their fire, "Greek Fire" was waterproof and continued to flame even on water. It is suspected that it was a predecessor to todays' napalm.
