Gutorm Gjessing Lecture 2025: The similar, the strange and the comparable. A Swedish traveller to Constantinople in the 1770s and his depiction of Islam and Muslims

The Swedish linguist Jacob Jonas Björnståhl spent three years in Istanbul during the late 1700s. His writings constitute a starting point for Nordic academic interest in Islam, with a focus on religious practices. Björnståhl depicts the Muslim world by means of comparisons, metaphors, and analogies in ways that point to the development of contemporary disciplines such as the study of religion, ethnography, and linguistics. The lecture is held by Professor Catharina Raudvere.

The Swedish linguist Jacob Jonas Björnståhl (1731–1779) spent three years in Istanbul, 1776–1779, and documented his observations in a diary and many travel letters which were published promptly when they reached Stockholm, Sweden. This correspondence was aimed for a qualified readership and soon appeared in German, Dutch and Italian translations. Björnståhl’s writings constitute a starting point for a Nordic academic interest in Islam and, unique for his time, with a distinctive emphasis on religious practices. Hence ritual spaces such as mosques and Sufi lodges play an important role in his writings.

Björnståhl was a learned writer, and the references in his work are exponents of the wide circulation of ’Turkish letters’ and other genres of travel literature. He displayed a special admiration for Lady Montagu with whom he shared the ambition to speak Turkish, made personal visits to people and places, criticizing previous travel accounts for repeating information without any effort to check the conditions in situ and the habit of wearing local dress. Björnståhl energetically mediates information from the sultan’s empire and builds up his authority as an ‘eyewitness’, to use the writer’s own phrasing. 

This presentation discusses how Björnståhl constructs a persona in his letters to give legitimacy to his observations. He declares his ambition to be “a European Traveller who wishes to write nothing but what he has seen, and what he knows for certain to be true”. As a man of the Enlightenment, his accumulative understanding of knowledge production dominates the letters; nonetheless, Björnståhl depicts Muslim world by means of comparisons, metaphors and analogies in ways that go beyond travel writing as a literary genre and point to the development of contemporary disciplines like the study of religion, ethnography and linguistics.
