 The writing on gun the Predator gives Harrigan says "Raphael Adolini  1715" refers to a Pirate who disappeared along with his crew in the  Burmuda Triangle in 1718. His ship was found, but the gun, a prized  possession of the Raphael Adolini, was missing. He was one of the  Pirates who flew a "Jolly Rouge", a red painted version of the  "Jolly Roger" that meant his crew took no prisoners.
