Juan Blas Covarrubias

A legendary and perhaps nonexistent pirate who supposedly flourished in the 19th century, long after the golden age of piracy. He is mentioned only in the diaries of captain Ainsworth Hampton-Folley.

According to another rumor, the "Last Great Spanish Pirate" was the great-great-grandson of another pirate, Blas Covarrubias Quintanilla. According to Hampton-Folley's account, Covarrubias's hoe was around Nazca, southern Peru. He was an autodidact, voracious reader an a polymath, devoted to the life of the mind. There was a rumor that Covarrubias had a treasure cache near Biabou on St. Vincent.

According to F.X. Caldeira, V.M. Straka sent a letter saying he has a map of Covarrubias's treasure and he won't have to worry about the business of selling stories. (416)

People who are fascinated by pirate stories, the Covarrubias Theorists, believe that Covarrubias wrote several narratives which were edited many years after his death. They tentatively point to The Spotted Cat that deals extensively with the Nazca Lines. Some of them go further saying that Straka boos contain hints to caches of buried treasure, pointing to the penultimate chapter of Ship of Theseus.

FXC mentions his Tortugan Journals but erroneously in the 17th century.
