In a letter by Gallo Galli to Duke Guidobaldo II. in 1566, he mentions having seen memoranda stating the cost of the Urbino palace at 200,000 ducats, the silver plate at 40,000, a set of tapestries representing the siege of Troy at 10,000, and the MSS. library at 40,000. Before leaving the subject we shall transcribe from the _Cortegiano_ an anecdote, not on account of its value, but as a specimen of the dull wit which Castiglione thought worth commemorating as the gossip of his model court. "Recollect also the silly trait, just related by our Lord Duke, of an abbé who, standing by while Duke Federigo was discussing what to do with the vast quantity of earth excavated from the foundations of this palace, exclaimed, 'My Lord, I have thought of a capital contrivance. Desire an immense ditch to be made, into which it may be put without more ado.' The Duke answered with a smile, 'And where shall we place the earth of the ditch itself?' To which the abbé replied, 'Make it big enough for both.' And though the Duke repeated that the larger it was the more earth would there be to remove, he never could see it, but went on saying, make it so much the greater!" Sanzi informs us that Federigo had intended to erect, in connection with this residence, a fane unequalled in regularity, beauty, and ornament, in order at once to manifest his piety and to provide a last home for his remains. The cathedral adjoining it, though founded by his father in 1439, was scarcely well begun until 1471, and when completed, in no way realised his project.[130] The church of S. Bernardino, also left unfinished at his death, was in some degree a substitute, being not only a special memorial of his piety, but supplying a mausoleum for himself and the few after members of his dynasty. [Footnote 130: Much confusion of dates has arisen regarding this church, owing to its slow advance,--unusually protracted even for Italy. Lazzarini tells that it was founded by Federigo in 1447, and consecrated to S. Crescentino in 1534, but that the façade was not completed till 1781. The cupola, planned by Muzio Oddi, was erected in 1604, but fell in 1789. The pulpit and organ were designed by Girolamo della Genga, and the latter was painted by Baroccio. The stuccoes were executed by Federigo Brandani, who died in 1575.]
