Липпо Мемми
Memmi's "Maestà" at San Gimignano is striking in the various methods of pastiglia and gilding work used. Golden tin on the throne cusps, laminated tin with gold foil for the halos which are carefully rendered with intricate punchwork, his application of these materials described as “a neat perfection rarely encountered elsewhere”. Examination of the motifs and degree of complexity in the punchwork has allowed historians to recognize the hand of Lippo Memmi and gives a clearer idea of his place in collaborations with Simone Martini. Stamp designs, gilding and the execution of rayed halos are similar, yet show that Lippo Memmi's mature gild and scribe work patterns in the 1317 "San Gimignano Maestà" are rooted in the simpler patterns and less developed line he applied to Martini's "Maestà" of 1315 at the Palazzo Pubblico in Siena.
