Jacob Masen[1] (28 March 1606 - 27 September 1681) was a German Jesuit priest, historian, dramatist and theologian.
Having entered the Order of Jesus in 1629, he taught poetry and rhetoric in the Lower Rhine region.
He completed a substantial antiquarian work on Trier by Christoph Brouwer.
[3] His epic poem Sarcotis (1654) became notorious in the 18th century, after William Lauder alleged that John Milton had plagiarised it in writing Paradise Lost.
[4] With Jacob Bidermann, he was one of the most important Jesuit dramatists influencing German drama.
