"Baldassare Castiglione (Italian: [baldasˈsaːre kastiʎˈʎoːne]; December 6, 1478 – February 2, 1529), count of Casatico, was an Italian courtier, diplomat, soldier and a prominent Renaissance author.
Castiglione wrote Il Cortegiano or The Book of the Courtier, a courtesy book dealing with questions of the etiquette and morality of the courtier. It was very influential in 16th-century European court circles." - (en.wikipedia.org 20.06.2021)
