Renaissance
Many argue that the ideas characterizing the Renaissance had their origin in late 13th-century Florence, in particular with the writings of Dante Alighieri (1265–1321) and Petrarch (1304–1374), as well as the paintings of Giotto di Bondone (1267–1337). Some writers date the Renaissance quite precisely; one proposed starting point is 1401, when the rival geniuses Lorenzo Ghiberti and Filippo Brunelleschi competed for the contract to build the bronze doors for the Baptistery of the Florence Cathedral (Ghiberti won). Others see more general competition between artists and polymaths such as Brunelleschi, Ghiberti, Donatello, and Masaccio for artistic commissions as sparking the creativity of the Renaissance. Yet it remains much debated why the Renaissance began in Italy, and why it began when it did. Accordingly, several theories have been put forward to explain its origins.
Visual art of the United States
The Harlem Renaissance was another significant development in American art. In the 1920s and 30s a new generation of educated and politically astute African-American men and women emerged who sponsored literary societies and art and industrial exhibitions to combat racist stereotypes. The movement, which showcased the range of talents within African-American communities, included artists from across America, but was centered in Harlem. The work of the Harlem painter and graphic artist Aaron Douglas and the photographer James VanDerZee became emblematic of the movement. Artists associated with the Harlem Renaissance include Romare Bearden, Jacob Lawrence, Charles Alston, Augusta Savage, Archibald Motley, Lois Mailou Jones, Palmer Hayden and Sargent Johnson.
