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.
Colonial Revival garden
The Colonial Revival gardening movement traces its origins to the Centennial International Exhibition of 1876, the first official World's Fair held in the United States. The Centennial Exposition was held in Philadelphia, Pennsylvania, from May 10 to November 10, 1876, and it celebrated the 100th anniversary of the signing of the Declaration of Independence. Although the Colonial Revival gardening movement had already begun a short time before, the Centennial Exposition created intense interest in all things colonial — including the colonial garden.
