The Arch of Augustus at Rimini was the model followed by Alberti in this façade. He intended to cover the church with a cupola, as may be seen from the design on a medal of Sigismondo Pandolfo Malatesta. See too the letter written by him to Matteo da Bastia, Alberti, Opere, vol. iv. p. 397.
This ancestral palace of the Medici passed in 1659 to the Marchese Gabriele Riccardi, from the Duke Francesco II.
Von Reumont, Lorenzo de' Medici, vol. ii. pp. 187-191, may be consulted for an interesting account of the building of this Casa Grande by Filippo Strozzi. The preparations were made with great caution, lest it should seem that a work too magnificent for a simple citizen was being undertaken; in particular, Filippo so contrived that the costly opus rusticum employed in the construction of the basement should appear to have been forced upon him. This is characteristic of Florence in the days of Cosimo. The foundation stone was laid in the morning of August 16, 1489, at the moment when the sun arose above the summits of the Casentino. The hour, prescribed by astrologers as propitious, had been settled by the horoscope; masses meanwhile were said in several churches, and alms distributed.
Antonio Filarete, or Averulino, architect and sculptor, was author of a treatise on the building of the ideal city, one of the most curious specimens of Renaissance fancy, to judge from the account rendered of the manuscript by Rio, vol. iii. pp. 321-328.
