Pietro Lorenzetti

 ( Sometimes called Pietro Laurati, Lorenzetti was an influential Italian painter born in Siena and active between 1306 and 1345. He was influenced by Giovanni Pisano (1250 – 1315) and Giotto (1267 – 1337), and also worked alongside the Sienese painter Simone Martini (1284 – 1344) at Assisi.

In their artistry were experiments with three-dimensional and spatial arrangements, which foreshadowed the art of the Renaissance. [...] )
