Alexander Morus

More's father, born in Scotland, was a rector at a Huguenot college in the town of Castres in Languedoc.

In 1654, John Milton launched a vitriolic attack upon him, in his Defensio Secunda, in the mistaken belief that he was the author of an anonymous Royalist work containing a "rabid" attack on Milton, called Regii sanguinis clamor ad coelum (Cry of the King's blood to Heaven).

Morus replied with Fides Publica in 1654, published like the Regii sanguinis by Adriaan Vlacq (also attacked by Milton).

The true authorship of the Regii sanguinis, written by Pierre Du Moulin, sent to Salmasius and only seen into print by Morus, came out in 1670.

[7] During his time at Amsterdam he completed the second edition of Joseph Justus Scaliger's Thesaurus temporum and had it published there in 1658.
