106. We shall now proceed to the situation and form of the villa. As regards situation; the villas of the Lago di Como are built, _par preference_, either on jutting promontories of low crag covered with olives, or on those parts of the shore where some mountain stream has carried out a bank of alluvium into the lake. One object proposed in this choice of situation is, to catch the breeze as it comes up the main opening of the hills, and to avoid the reflection of the sun's rays from the rocks of the actual shore; and another is, to obtain a prospect up or down the lake, and of the hills on whose projection the villa is built: but the effect of this choice when the building is considered the object, is to carry it exactly into the place where it ought to be, far from the steep precipice and dark mountain, to the border of the winding bay and citron-scented cape, where it stands at once conspicuous and in peace. For instance, in the view of Villa Serbelloni[16] from across the lake, although the eye falls suddenly from the crags above to the promontory below, yet all the sublime and severe features of the scene are kept in the distance, and the villa itself is mingled with graceful lines, and embosomed in rich vegetation. The promontory separates the Lake of Lecco from that of Como, properly so-called, and is three miles from the opposite shore, which gives room enough for aerial perspective. [Footnote 16: [Villa Serbelloni, now the dependence of the Hotel Grande Bretagne at Bellaggio, and Villa Somma-Riva, now called Villa Carlotta, at Cadenabbia, and visited by every tourist for its collection of modern statuary, are both too well known to need illustration by the very poor wood-cuts which accompanied this chapter in the "Architectural Magazine." The original drawings are lost; judging from that of the cottage in Val d'Aosta we may safely believe that they were most inadequately represented by the old cuts.]] 107. We shall now consider the form of the villa. It is generally the apex of a series of artificial terraces, which conduct through its gardens to the water. These are formal in their design, but extensive, wide, and majestic in their slope, the steps being generally about 1/2 ft. high and 4-1/2 ft. wide (sometimes however much deeper). They are generally supported by white wall, strengthened by unfilled arches, the angles being turned by sculptured pedestals, surmounted by statues, or urns. Along the terraces are carried rows, sometimes of cypress, more frequently of orange or lemon trees, with myrtles, sweet bay, and aloes, intermingled, but always with dark and spiry cypresses occurring in groups; and attached to these terraces, or to the villa itself, are series of arched grottoes built (or sometimes cut in the rock) for coolness, frequently overhanging the water, kept dark and fresh, and altogether delicious to the feelings. A good instance of these united peculiarities is seen in Villa Somma-Riva, Lago di Como.
