Autograph Letter Signed, asking for permission to see books from the Vatican Library. In Italian. 2 pp. 8 x 5 inches, fine. Rome, 14 September 1878. Eduard Winkelmann (1838-1896), German historian. Winkelmann wrote a Geschichte der Angelsachsen bis zum Tode König Ælfreds (Berlin, 1883); and his residence in Russia induced him to compile a Bibliotheca Livoniae historica (St Petersburg, 1869–1870, and Berlin, 1878); but his chief works deal with the history of the Holy Roman Empire during the Later Middle Ages.
