Adam Olearius

Adam Olearius (born Adam Ölschläger or Oehlschlaeger, September 24, 1599 – February 22, 1671), was a German scholar, mathematician, geographer and librarian. He became secretary to the ambassador sent by Frederick III, Duke of Holstein-Gottorp, to the Shah of Safavid Persia (Iran), and published two books about the events and observations during his travels.

He was born at Aschersleben, near Magdeburg. After studying at Leipzig he became librarian and court mathematician to Frederick III, and in 1633 he was appointed secretary to the ambassadors Philipp Crusius, jurisconsult, and Otto Bruggemann, a merchant from Hamburg, sent by the duke to Muscovy and Persia in the hope of making arrangements by which his newly founded city of Friedrichstadt should become the terminus of an overland silk-trade. This embassy started from Gottorp on 22 October 1633 and travelled by Hamburg, Lübeck, Riga, Dorpat (five months' stay), Reval, Narva, Ladoga, and Novgorod to Moscow (14 August 1634). Here they concluded an advantageous treaty with Tsar Michael of Russia, and returned forthwith to Gottorp (14 December 1634 – 7 April 1635) to procure the ratification of this arrangement from the duke, before proceeding to Persia.
