Thomas Plowden

[2] As was the case with his contemporary Nathaniel Bacon, English Jesuits, given their illegal status as recusants, often published under assumed names.

Plowden presented his translations under the name of the distinguished Welsh Salusbury family.

Plowden translated Daniello Bartoli's 1645 L'huomo di lettere into English as The Learned Man Defended and Reformed, dedicating it to George Monk and William Prynne.

It was published in 1660 by William Leybourn, and sold by Thomas Dring "near St. Dunstan's Church" on Fleet Street.

The next year, the same printer published Mathematical Collections, with translations of Galileo's Dialogue Concerning the Two Chief World Systems, as well as works of Kepler, Castelli, Tartaglia, and other significant European Restoration authors.
