The Palace and Park by Phillips, Forbes, Latham, Owen, Scharf, and Shenton

18. _Ambulatory, Ambulatio_, also called _Porticus_ by the Romans, and

_Stoa_ by the Greeks, is a colonnade on four sides, very like the cloisters of our cathedrals. The view looking through the fauces is bounded by a small shrine or chapel, called the _Lararium_. It is a niche raised on a pedestal, flanked by pilasters, and surmounted by a pediment. Within this were kept the Lares, the sacred household gods, that accompanied the inhabitants in their flight. No figures of this sort have ever been found in such places at Pompeii, although many representations of them remain depicted on the walls. They were generally represented as young men in short girt tunics, crowned and holding the drinking horn in one hand. (See Milman’s Horace, p. 168.) Their appearance was first ascertained by an inscription over the sculpture of an altar formerly in the Villa Medici, and now at Florence; a similar altar is in the Vatican, both inscribed LARIBVS AVGVSTIS. (See Galleria di Firenze, pl. 144 of statue, &c.; Mus. Pio. Clem., vol. iv., tav. 45; and Guattani Mon. Ined, vol. ii.; Maggio, 1785). The Lares presided especially over the domestic hearth. The cornice and entablature of Lararium are taken from the funeral Triclinium at Pompeii. The wall behind is a rich Pompeian red, with a yellow ornament, forming a panel on it, beautifully painted. The roof of the ambulatory is panelled and decorated according to the prevailing style of the lighter coloured ceilings at Pompeii. The devices are formed of very thin lines of the brightest colours upon white. The Ionic capitals of the columns are from the Basilica. The shafts of the columns are not fluted at the lower part, the remaining unfluted surface, together with the mouldings upon the base, are painted bright red. This is a Pompeian peculiarity. Red is a prevailing colour at Pompeii, but in the House of the Surgical Instruments, the lower part of the columns was blue, a dwarf wall between them being painted red.
