Divine Comedy (c. 1308–1320), however, Dante changes his view to another that treats the Adamic language as the product of Adam. This had the consequence that it could no longer be regarded as immutable, and hence Hebrew could not be regarded as identical with the language of Paradise. Dante concludes (Paradiso XXVI) that Hebrew is a derivative of the language of Adam. In particular, the chief Hebrew name for God in scholastic tradition, El, must be derived of a different Adamic name for God, which Dante gives as I. Before the acceptance of the Indo-European language family, these languages were considered to be "Japhetite" by some authors (e.g., Rasmus Rask in 1815; see Indo-European studies). Beginning in Renaissance Europe, priority over Hebrew was claimed for the alleged Japhetic languages, which were supposedly never corrupted because their speakers had not participated in the construction of the Tower of Babel. Among the candidates for a living descendant of the Adamic language were: Gaelic (see Auraicept na n-Éces); Tuscan (Giovanni Battista Gelli, 1542, Piero Francesco Giambullari, 1564); Dutch (Goropius Becanus, 1569, Abraham Mylius, 1612); Swedish (Olaus Rudbeck, 1675); German (Georg Philipp Harsdörffer, 1641, Schottel, 1641). The Swedish physician Andreas Kempe wrote a satirical tract in 1688, where he made fun of the contest between the European nationalists to claim their native tongue as the Adamic language. Caricaturing the attempts by the Swede Olaus Rudbeck to pronounce Swedish the original language of mankind, Kempe wrote a scathing parody where Adam spoke Danish, God spoke Swedish, and the serpent French. The primacy of Hebrew was still defended by some authors until the emergence of modern linguistics in the second half of the 18th century, e.g. by (1648–1705) in A philosophicall essay for the reunion of the languages, or, the art of knowing all by the mastery of one (1675) and by Gottfried Hensel (1687–1767) in his Synopsis Universae Philologiae (1741). Linguistics For a long time, historical linguistics wrestled with the idea of a single original language. In the Middle Ages and down to the 17th century, attempts were made to identify a living descendant of the Adamic language. Multiplication of languages The literal belief that the world's linguistic variety originated with the tower of Babel is pseudolinguistics, and is contrary to the known facts about the origin and history of languages. In the biblical introduction of the Tower of Babel account, in Genesis 11:1, it
