Despite there being only one working day in the last week of 2019, the Vatican managed to add 22 new manuscripts. One of the prettier ones is a copy of Agostino Steuco's De Philosophia Perenni, Vat.lat.6377. This is a work of the high Counter-Reformation which tries to prove, in ten books, that ALL of ancient philosophy was actually entirely compatible and, in fact entirely in harmony with Roman Catholicism. Right before the start of the text, on f.18r, is a dedication letter to Pope Paul III in a lovely example of the control of a professional scribe: 14 lines precisely justified and then a descending triangle of text to fill the page, f.17v on the right

The bottom border if from f.1r of Vat.lat.3360
