Then Fernach began to say that Johannes di Firimburg was right, and that the proportions of the church, with which his sacristy had to harmonize, were wrong. On this the President, the Archbishop, and the Deputies sent to Piacenza for an expert, named Gabriele Stornaloco, a great geometrician, to settle the vexed question. He came, made his calculations, and decided that the German critics were in the wrong. Not satisfied with this, they next prayed the Duke to send his sculptor, Bernardo da Venezia, to give his opinion. He came to Milan in November 1391, made his computations, and also decided that the Germans had made a mistake. Then Fernach's plan for the sacristy was handed over to the chief architect, Jacopo da Campione, to modify its proportions; and Fernach's name appears no more in the books of the _spenditore_. Another German in the _laborerium_ was an architect, Magister Enrico or Ulrico di Ensingen, near Ulm. He came in July 1391, but only remained a few months, and then disappeared. Another Enrico or Ulrico (the _spenditore's_ orthography is diverse and mixed) da Gamodia or Gmunden, then appears. This is the Heinrich of Gmunden, whom the guide-books generally name as the architect of the Duomo. We will now see precisely how much was due to him. His name appears at a meeting on May 1, 1392, in which Jacopo da Campione, as usual, holds the first place. Enrico da Gamodia, as he is written in the books, was but lately _returned_ (_ritornato_) from Germany, and had offered himself to design and work in the building of the Duomo. He allowed himself to raise doubts and express censure of the solidity and strength of the work already done. Public discussions were raised as to the validity of his objections. A great meeting was called, in which his name appears at the bottom of a long list of Masters, all Italian. To the questions as to the solidity and beauty of the building, and whether it should be continued on the same plan or not, all the other Masters agreed that the design could not be improved. Heinrich of Gmunden alone answered stubbornly, _non assensit_. The guild soon after decided on cutting off useless expenses, and among others the salary of Magister Heinrich, who was "dismissed," and "sent about his business" (licentietur ad eundum pro factis suis). The German appealed to the Duke of Milan, who begged the Deputati to reconsider their decision. They, however, held firm, and calling Heinrich before them on the 7th of the following July, told him that he had not served the cause well (in designamentis et aliis necessariis pro Fabrica male serviverit). They gave him six florins for his journey and dismissed him. "Yet," as Merzario says,[268] "to this man who came to Milan at the end of 1391, and left in the middle of 1392, is given by many people the credit of having designed the Duomo of Milan, which was begun in 1386, and also of the Certosa of Pavia begun in 1396."
