"the Swedes in 1679 decided to establish diplomatic relations with Iran. The man chosen to lead the delegation dispatched for that purpose, Ludvig Fabritius, was a Brazilian-born Dutchman who had made a career in the Russian military. Captured during the Sten' ka Razin rebellion in 1670, he had managed to escape to Iran, spending some time in Isfahan."
