Pedro Sarmiento de Gamboa, Viage al Estrecho de Magallanes (Madrid, 1768)

The royal press at Madrid printed Sarmiento's 1579-80 journal of the Strait of Magellan in 1768, and bound in front of it a dossier of testimonies from other writers, Spanish and foreign. The journal shows what a survey looked like from inside: soundings, a stone cairn, a cross visible down the whole channel. The testimonies show what came of it: a garrison of four hundred set to close the Strait, and corpses left clothed in the houses.
