Idiosyncrasy vs. Mannerism — What's the Difference?

An idiosyncrasy is an unusual feature of a person (though there are also other uses, see below). It can also mean an odd habit.

Mannerism, also known as Late Renaissance, is a style in European art that emerged in the later years of the Italian High Renaissance around 1520, spreading by about 1530 and lasting until about the end of the 16th century in Italy, when the Baroque style largely replaced it. Northern Mannerism continued into the early 17th century.Stylistically, Mannerism encompasses a variety of approaches influenced by, and reacting to, the harmonious ideals associated with artists such as Leonardo da Vinci, Raphael, and early Michelangelo.
