Finding the Southern Mainland at all costs is the goal set by Kyros, one of the most remarkable navigators of the Great Geographical Discoveries. Quiros was right when he argued that the mainland should be southwest of the Santa Cruz Islands. And he was right to believe that Southland was easier and easier to reach, coming from Peru, from east to west. Two voyages were made by Kyros in the latitudes of the Pacific Ocean unknown at that time. And through no fault of his, his brilliant projects remained unfulfilled. This book is dedicated to him, a man of amazing fate, who predicted the existence of Australia and Antarctica, with whose name the most outstanding voyages of the late XVI - early XVII centuries are associated.
