Jean Dulaien was a French privateer turned pirate active in the Caribbean from 1727 to 1728. He was eventually pardoned, but later imprisoned. His final fate is unknown. This flag was attributed to him in a letter written by the Mayor of Nantes, Monsieur Mellier: “Ce pavillion … est faite d’étoffe noire sur laquelle se détachaient des marques blanches comme figures de testes coupées au coutelas, restes d’ossments et sabliers.” “This flag … is made of black cloth, on which there are white marks, such as figures of heads cut of with a cutlass [skulls], piles of bones and hourglasses.” Maurice Besson, Les Frères de la Coste (1928), p. 231.
