Johannes Loccenius (Johan Locken)[1] (13 March 1598 – 27 July 1677) was a German jurist and historian, known as an academic in Sweden.
[3] As librarian also at the University of Uppsala, he received the embassy of Bulstrode Whitelocke, and they discussed English jurists including Francis Bacon and John Selden.
[8] As legal antiquarian Loccenius published an edition of the corpus of Swedish provincial law, the Lex Sueo-Gothorum.
[9] His Synopsis juris ad leges Sueticas accommodata (1648) was an early example of the 17th-century use of the Decalogue to classify capital crimes.
He initially minimised the pre-Christian period, and he followed Ericus Olai in arguing that foreign kings were responsible for negative aspects of the history.
