[1] First employed as a teacher at Monza, he finally settled down in Milan, as a professor of rhetoric at the Archiepiscopal seminary, only after several years of indecision about accepting an offer to accompany the retiring governor to Spain.

[1] The task of the doctors of the Ambrosiana was primarily the study of manuscripts and printed books, from which they might publish old texts or learned dissertations in history or philosophy.

[7] In 1617, when the first volume of his Historia Ecclesiae Mediolanensis appeared to much praise, there was also criticism from many who did not look favourably on some of the passages of the work, and judged them unedifying.

This volume covered Milanese history from 1313 to 1558, that is, until the era of Charles V; in 1641 De peste was also released, a fundamentally important record of that recent painful tragedy.

However he left the material ready for the continuation of the work: three other printed volumes followed between 1646 and 1648, the first two edited by Stefano Sclatter, and the third by Orazio Landi.

[7] Charles Mackay in his Extraordinary Popular Delusions and the Madness of Crowds (1841), which contains a sections on the Milan plague, used Ripamonti's De peste as a primary source.
