The positions of 135 stars were then included by Peter Plancius in his sky maps. Dorado or then known ‘Den Dorado’ was one of the recognized twelve new ones. The Dorado is a name of a tropical oceans predator that has offered the crew a variety from the usual food. Dorado means swordfish or dolphinfish in Spain.
