What is the full name of the person who is alleged to have instructed that the windows be larger than the entrance of the Palazzo Medici?
The construction of this severe and forbidding building was commissioned in 1458 by the Florentine banker Luca Pitti (1398-1472), a principal supporter and friend of Cosimo de' Medici. The early history of the Palazzo Pitti is a mixture of fact and myth. Pitti is alleged to have instructed that the windows be larger than the entrance of the Palazzo Medici.  The 16th-century art historian Giorgio Vasari proposed that Brunelleschi was the palazzo's architect, and that his pupil Luca Fancelli was merely his assistant in the task, but today it is Fancelli who is generally credited. Besides obvious differences from the elder architect's style, Brunelleschi died 12 years before construction of the palazzo began. The design and fenestration suggest that the unknown architect was more experienced in utilitarian domestic architecture than in the humanist rules defined by Alberti in his book De Re Aedificatoria.Though impressive, the original palazzo would have been no rival to the Florentine Medici residences in terms of either size or content. Whoever the architect of the Palazzo Pitti was, he was moving against the contemporary flow of fashion.  The rusticated stonework gives the palazzo a severe and powerful atmosphere, reinforced by the three-times-repeated series of seven arch-headed apertures, reminiscent of a Roman aqueduct. The Roman-style architecture appealed to the Florentine love of the new style all'antica.  This original design has withstood the test of time: the repetitive formula of the façade was continued during the subsequent additions to the palazzo, and its influence can be seen in numerous 16th-century imitations and 19th-century revivals. Work stopped after Pitti suffered financial losses following the death of Cosimo de' Medici in 1464.  Luca Pitti died in 1472 with the building unfinished.
