The Sienese had, as we have said, proposed to so enlarge the church by adding a huge nave, that the present church would only form the transept. This was begun, but when the works had already advanced the plan was abandoned. Provisional _Magistri_ were called to form a committee, which met in council on February 17, 1321, and here, for the first time in Siena, we find Lorenzo Maitani giving his vote. He was called to attend the meeting from Orvieto, where he had been _capo maestro_ of the works from 1310. He, with Niccola Nuti, Gino di Francesco, Tone di Giovanni, and Vanni di Cione (one of Orcagna's relatives from Florence), formed the council. After due deliberation they pronounced on the inconvenience of proceeding with the addition to the Duomo, and decided to build a new church of more moderate dimensions, which should still be large and magnificent. The work now continued without interruption; and on November 20, 1333, we find another Council of Masters was called, in which twelve of the guild severally swear "testis juratis die supra scripta et sancta Dei evangelia, corporaliter tactis scripturis dicere veritatem, suo juramento testificando dixit," etc., that the walls and foundations were strong and firm. [Illustration: FRONT OF SIENA CATHEDRAL. DESIGNED BY MAGISTER GIOVANNI PISANO. _See page 295._] The next _capo maestro_ was Master Lando or Orlando di Pieri, son of Piero, a metal-worker of the guild, who was recalled from Naples in 1339. He was a Lombard, though a naturalized citizen of Siena. They say Lando is "a most legal man (_omo legalissimus_), not only in his own special branch (gold-working), but in many others; is a man of the greatest ingenuity and invention, both with regard to the building of churches and the erection of palaces and private houses; a good engineer for roads, bridges, or fountains, and, above all, a citizen of Siena."[225] Here we see signs of the jealousy of the Lombard Guild, which caused the schism of which we have spoken. Lando was truly an acknowledged genius. He made the coronet with which the Emperor Henry VII. was crowned at Milan in 1311. Muratori (cap. xiii.), quoting an old Latin dissertation on the "corona ferrea," says the maker of the crown was present, "presente magistro Lando de Senis, aurifabro predicti domini Regis, qui predictam coronam propriis manibus fabricavit." We hear no more of his gold work; but in 1322 he was employed in Florence to hang the great bell of the palace of the Signoria, and make it ring (Ita quod de facili pulsatur et pulsari potest), for which he was paid 300 gold florins. In his architectural capacity he was employed at Naples by King Robert of Anjou, but was recalled from there to Siena in 1339, and made _caput magister_ of the builders of the Duomo. The contract, signed on December 3, 1339, binds him for three years at a salary of 200 lire a year.
