Leon Battista Alberti was born in Genoa in 1404 and lived until 1472, and in many ways he was the successor of Brunelleschi in terms of Renaissance Architecture. While Brunelleschi developed a linear style, Alberti experimented with ideas of plasticity. Alberti was a theorist in the Humanist arts, he was well educated and lived a peripatetic life. He also wrote several treatises. The Ten Books of Architecture, written in 1452 in response to Vitruvius, differentiates Greek and Roman architecture. Alberti was not well versed in the actual process of building, he applied his studies and theories to the conceptual aspect. He was concerned with proportion, the orders, and ideal town planning. In 1455 the construction of the Palazzo Rucellai had begun.
