Renaissance (n.)

"great period of revival of classical-based art and learning in Europe that began in the fourteenth century," 1840, from French renaissance des lettres, from Old French renaissance, literally "rebirth," usually in a spiritual sense, from renastre "grow anew" (of plants), "be reborn" (Modern French renaître), from Vulgar Latin *renascere, from Latin renasci "be born again, rise again, reappear, be renewed," from re- "again" (see re-) + nasci "be born" (Old Latin gnasci, from PIE root *gene- "give birth, beget").

An earlier term for it was revival of learning (1785). In general usage, with a lower-case r-, "a revival" of anything that has long been in decay or disuse (especially of learning, literature, art), it is attested by 1855.

[Renaissance] was so far established as the English word for the thing before it was latinized or anglicized into renascence that it is still the more intelligible of the two, & may well be left in possession. [Henry W. Fowler, "Modern English Usage," Oxford: 1926. He does, however, recommend pronouncing it as English, "rinā'sns."]

As an adjective, "of or pertaining to the Renaissance," by 1842.

Renaissance man is attested by 1885, literally, "a man alive during the Renaissance." By 1898 it was used particularly to express "exhibiting the virtues and characteristics of an idealized man of the Renaissance" (humanism, scholarship, varied attainments, freedom of thought and personality); in reference to modern or living persons, it is attested by 1949 and sometimes means merely "well-rounded."
