Engravings from Agostino Tensini’s “Le meraviglie della penna conchiudenti in diversi modi di scrivere delineati, et intagliati.” Published in 1641, it is an extremely rare first edition of a Baroque Italian calligraphy manual. All of these taken from the website of the antiquarian bookseller Martayan Lan some of whose wares I saw at an antiquarian book fair recently though, alas, not these.
