Maria Graham, an aristocratic Englishwoman later to become Lady Calcott, was an acute observer with a sprightly literary style. As she sailed into the Bay of All Saints in 1824, she was enthralled by the scene, and she and her shipboard companions amused themselves by speculating as to on which shore before them Robinson Crusoe had established his plantation, for Defoe's hero was supposed to have lived here too. No traveler who crossed the bar of Santo Antônio and sailed beneath the fort of that name that guarded it remained unimpressed by the beauty of the prospect that greeted their eyes. At latitude 13 degrees south, longitude 37–9 degrees west, the sea cuts a great arm into the tropical coastline, forming a magnificent bay or inland sea some fifty miles in length.
