Ottoman envoy's 1720–21 embassy to France
In 1720 Sultan Ahmed III and Grand Vizier Nevşehirli İbrahim Pasha sent Yirmisekiz Mehmed Çelebi to the court of the eleven-year-old Louis XV. He was instructed to visit fortresses and factories and report on French means of civilization and education that might be applied at home. He travelled from Toulon along the Canal du Midi to Paris and recorded Versailles, Marly, the Paris Observatory, the Gobelins manufactory, the Jardin du Roi and the opera. His son Said Mehmed, who travelled with him, later helped İbrahim Müteferrika set up the first Ottoman Turkish-script printing press in 1727.
