An unusual writing book with extensive text including woodcut letterforms in the first part. The use of intaglio and woodcut is reversed in the second part, where the double-page engravings include extensive text.
Royllet, a pupil of the writing master Louis Rossignol, was the son of a carpenter in Châlons-en-Champagne. He worked at the Trésor royal (the finance ministry in the anciene regime) and was admited to the Communauté des maîtres écrivains in 1729.
Collations of copies vary. I have compared this copy with the Columbia copy, which has some of the same plates and some different. The Harvard copy is made up with plates from a later issue.
OCLC locates copies at Amsterdam University, BNF, BL, Newberry Library (probably in error as only the 1772 is in their online catalogue) and Columbia.
