Baldassare Castiglione (born 6 December, 1478; died 2 February, 1529), pictured above in the portrait made between 1514 and 1515 by Raphael (1483-1520); in the collection of the Musée du Louvre, Paris
Usar in ogni cosa una certa sprezzatura, che nasconda l’arte e dimostri ciò che si fa e dice venir fatto senza fatica e quasi senza pensarvi.
Practise in everything a certain nonchalance that shall conceal design and show that what is done and said is done without effort and almost without thought.
— from Il Libro del Cortegiano (The Book of the Courtier) (1528)
