After studying
philology at the Erfurt academy and at
Leiden, he travelled in order to increase his
linguistic knowledge. While searching in
Rome for some documents at the request of the Swedish Court (1649), he became friends with
Abba Gorgoryos, a monk from the
Ethiopian province of
Amhara, and acquired from him an intimate knowledge of the
Ethiopian language of Amhara. In 1652 he entered the service of the duke of
Saxe-Gotha, in which he continued until 1678, when he retired to
Frankfurt am Main. In 1683 he visited
England to promote a cherished scheme for establishing trade with Ethiopia, but his efforts were unsuccessful, chiefly due to the resistance of the authorities of the
Ethiopian Orthodox Church. Returning to Frankfurt in 1684, he devoted himself wholly to literary work, which he continued almost to his death. In 1690 he was appointed president of the
Collegium Imperiale Historicum. His correspondence with
Leibniz on linguistics was published in 1755 by August Benedict Michaelis. Ludolf died at Frankfurt. ==Works==
