Reading edition
Page 24, l. 19. “Scripts of Mart.”—Letters of marque. “Mart, originally for Mars. It was probably this use of mart that led so many authors to use letters of mart, instead of marque, supposing it to mean letters of war. Under this persuasion Drayton put ‘script of mart’ as equivalent” (Nares).
