"De la Havana al Puerto de Tampa, Año de 1757, Diario de Reconocimientos, Oceano Atlantico Septentrional" by Don Francisco Maria Celi is unquestionably a key document in Florida history and the history of Tampa Bay. The chronology of its recent discovery is not too complicated. Celi, “Pilot of the Royal Spanish Navy” and commander of the Florida expedition, carefully prepared a useful and artistically beautiful map that went with his report. This map (actually there were two versions) was known to modern historians, but the accompanying report was not. The late Clarence Simpson had knowledge of the Celi map, as did the Latin American history specialist, Arthur P. Whitaker, who made reference to it in 1931. Florida historian Mark F. Boyd and Florida archaeologist Ripley Bullen recalled having seen the map during the course of their research, but none of these social scientists had specified the archival origin or the historical particulars of the map.
