Almost all art critics ascribe also to him the design of the originally Villa Chigi, now Villa Farnesina. In this villa, two wings branch off from a central hall with a simple arrangement of pilasters, and a decorative frieze on the exterior of the building [1]. The frescoed paintings which adorn the interior rooms are for the most part by Peruzzi. One example is the Sala delle Prospettive, in which Peruzzi revived the perspective schemers of Melozzo da Forli and Mantegna, possibly under the influence of both. The walls the room are painted so that when one stands toward the left, one has the illusion that one is staning in an open-air terrace, lined by pillars, looking out over a continuous landscape. The decoration of the façade, the work of Peruzzi, has almost entirely vanished, but it is documented in a drawing by an anonymous French artist in the New York Metropolitan Museum of Art [2]. To decorate this villa on the Tiber many artists were employed, and just as the style of the villa in no wise recalls the old castellated type of country-house, so the paintings in harmony with the pleasure-loving spirits of the time were thoroughly antique and uninspired by Christian ideas
