De iusto imperio Lusitanorum Asiatico. [...] Ad Philippum IIII. potentissimum Hispaniarum, & Indiarum monarcham.
4to. (8), 190, (28) ff. Title printed in red and black with woodcut arms of Spain. Modern brown calf, gilt spine in five compartments with two red labels.
Rare first edition. The principal printed justification of Portugal's imperial claims in the East Indies in the face of the attack posed by Hugo Grotius's "Mare liberum". Freitas's treatise is a powerful refutation of Grotius, claiming that the sovereign has the right to refuse admission of commerce or foreigners to his territory and forbid his subjects all trade and intercourse with them.
Calf somewhat worn. Some minor marginal dampstaining and foxing, with some 20 leaves quite heavily browned. From the library of Swedish antiquarian bookdealer Björn Löwendahl (1941-2013).
