THE MANNERIST CONCEPTION OB SPACE accent of the composition towards the River Arno. Here a loggia, open in a spacious Venetian window on the ground floorand originally also in a colonnade on the upper floor, replaces the solid wall. This is a favourite Mannerist way of linking room withroom, away in which both a clear Renaissance separation of units and a free Baroque flow through the whole and beyond are avoided. Thus, Palladio's two Venetian churches terminate in the east, not in closed apses, but in arcades—straight in S. Giorgio Maggiore (1565), semicircular in the Redentore (157?)—behind which back rooms of indistinguishable dimensions appear. And thus Vasari, together with Vignola (1507-73) designed the Villa Giulia, the country casino of Pope Julius III (1550- 55), as a sequence ofbuildings with loggias towards semicircular courts T.rt-TTTTTT/w 59.

For the garden of the i6th century is still walled in. It may have long and varied vistas, as you also find them at the Villa Este in Tivoli or at Caprarola, but they do not stretch out into infinity as in the Baroque at Versailles. Neither do the low colonnades on the ground floors of Mannerist buildings, such as the Palazzo Massimi and the Uffizi, indicate infinity—that is, a dark, unsurveyable back- ground of space, as a Rembrandt background. Back walls are too near. The continuity of the facade is broken by such colonnades— that is what the Renaissance would have disliked—but the layer of opened-up space is shallow and clearly confined in depth, Pafladio's E.A.—9 in
