Buschetus (Busketus, Buschetto)
The first architect of the cathedral of Pisa. The date, 1006, in the inscription of his monument, which still stands in the cathedral, is probably that of the commensement of the building. The inscription of the fašade, with the date 1063, is supposed to refer to a subsequent enlargement (Mothes, Vol. II, p. 722). In a contract of December 2, 1105, Buschetto is mentioned as one of four architects who had worked on the cathedral; the others being Uberto, Leone, and Signoretto. He was probably a Byzantine Greek.
