"Whereas, we, deeming those men to be worthy of distinction and preference who are gifted with such genius and talent as have been in all ages esteemed, especially for architecture founded upon arithmetic and geometry, which, as foremost among the seven liberal arts, and as depending upon exact science, require profound knowledge and great ability, and are therefore highly appreciated by us; and whereas, we, having sought everywhere, but particularly in Tuscany, the fountain of architects, without finding any one really versant and skilful in that profession, and having lately heard by report, and since ascertained by full experience, the learning and attainments of the distinguished Messer Lutiano, bearer hereof; and, further, we, having resolved to erect in our city of Urbino a fair residence, in all respects befitting the rank and reputation of our predecessors and ourselves,--have, for these causes, selected the said Messer Lutiano as engineer and chief of all those employed upon that fabric, in building, hewing, woodwork," &c. &c. The deed goes on to enjoin upon all the workmen implicit obedience to his orders, and to authorise his entire control over them, and over the funds destined for the palace.[120] [Footnote 120: GAYE, _Carteggio d'Artisti_, I., p. 214, and PUNGILEONE, _Elogio di Bramante_, 63. The original is in Latin.] Although the date of this patent may appear inconsistent with that already adopted for the foundation of the _Corte_, as this residence was usually called, it is clear, from other documents printed along with it, that operations were already considerably advanced under the superintendence of Luziano. In the preceding year we find him designed the Count's engineer, acting as a sort of clerk of the works, and litigating with a builder from Como regarding measurements of masonry; indeed, he seems to have continued these duties until his death at Pesaro, soon after that of his patron, whose liberality enabled him to leave considerable property to his children.
