VARRO’S MAGNIFICENT AVIARY.--Adjoining his villa was a part of the house called the Ornithon, or the Aviary, of which some ruins are still remaining, between the two small rivers Vinius and Casinus, but can hardly be made out. More, perhaps, was in existence when the famous architect and antiquarian, Pierre Ligorio, drew the plan and profile more than 200 years ago. This drawing of Plate IX. is conformable with Varro’s own description, who says that: “At the entrance there are two porticoes, or two large cages (in the Plate these are omitted for want of space); they are buildings with colonnades all round, on the top and sides there are nettings spread to prevent the escape of the birds. The entrance to the yards is between the two pavilions; two basins, long and wide, are alongside of the court-yard on the right and left of it; from them you pass to the grand double colonnade, the first circumference of which is of stone, and the second of pine; the distance from each other is five feet, and the whole of this middle space is filled with birds, which are prevented from escaping by small fillets all over the top and sides. There are, between the columns, like a small theatre, rails, like steps, put forward for the birds to perch upon. There are birds of various species, particularly singing birds, such as nightingales and blackbirds; a small canal supplies them with fresh water, and they are fed from under the netting. Facing the pedestals of the column is a stone, raised one foot nine inches above the quay, and that is elevated two feet above the level of the water; its width is five feet, to enable the visitor to walk round. At the lower part of the quay, on the water-side, there are holes practised where the ducks can retire. In the centre of the large basin, about 200 feet in diameter, is a small island, bordered by a small colonnade, under which Varro treats his friends; in the middle, a round table, which a servant turns on a pivot, so that in succession the guests are supplied with dishes, plates, cups, and goblets. There is seen also an hemisphere, where the star Lucifer turns in the day, and Hesperus at night; both mark the hour, and are variable; on the same hemisphere the winds, to the number of eight, are marked with a hand that is always moving as the wind changes, the same as the clock of Cyprestus, at Athena.” The drawing of this Aviary is beautiful. It appears that Pierre Ligorio followed Varro’s description; at all events, the drawing of this Plate perfectly agrees with it.
