A New Arabic Nautical Manuscript in Lisbon


  • 1. Centro Interuniversitário de História das Ciências e da Tecnologia, Faculdade de Ciências, Universidade de Lisboa


A previously unstudied Arabic nautical autograph manuscript has been recently
brought to light in Lisbon. An early nineteenth-century bundle including at least
three distinct works in almost one hundred leaves, it contains stellar route bearings
and coastal descriptions, extensive astronomical, geographical, and traverse tables,
in addition to a number of Islamic ethical sections and Sufi prayers. While the textual
tradition remains inconclusive, authorship rests partly with an ʿAbd Allāh b. Aḥmad
b. ʿAbd al-Razzāq, from Ṣūr. The main physical and textual features are given here
to lay the ground for further study.
