"Even if a man has entered a field against the will of the owner he takes possession of his spoils." -Alberico Gentili, Hispanicae Advocationis Libri Duo (1921) Hispanicae Advocationis Libri Duo, Volume I (1921) by Alberico Gentili was originally published in Latin in 1613 posthumously at his request. This volume is a replica of the 1921 edition with only the original Latin text. The book was written in support of the claims made by the Spanish Armada and outlines international rules in war and peacetime. While legal writing of the time consisted of theory and generalities, Gentili outlined actual cases of the time period and applied the principles of international law to them. Considered a reference for international law, this is a must-read for all interested in its history.
