In the immediate eastern suburb of _Aquinum_, a few hundred metres from the Porta San Lorenzo on the via Latina, stands the church dedicated to San Tommaso, which in the Roman period was situated immediately outside the urban area of _Aquinum_. In fact, numerous funerary, inscription and sculptural finds come from this area, partially dispersed, partially housed in Aquino museum, partly incorporated into the boundary wall of via degli Orefici or, lastly, reused in the structures of the church of San Tommaso. Among these the recent discovery of a funerary altar, reused in the building of medieval structures neighbouring the church. The altar is of the type with small twisted columns and triangular cyma finishing in two quarter-circle rounded acrotyria decorated with tragic masques. At the centre of the pediment, in a lunette, are two sea-monsters or snakes facing each other and separated by a trident. On the sides are two winged geni with upside down torches. The find falls within the typology of altars or funerary altars in use between the 1st century B.C. and the 2nd century A.D. (with examples also of 3rd century A.D. date), and in particular in that of altars with commemorative functions, on which libations could be poured. However, although the decorative motifs and the eschatological significance of the symbols are those common to funerary altars, the stylistic carelessness suggests it was locally produced by an artisan who seems to have roughly copied the subjects depicted from models in circulation, without fully understanding their significance. The evidence of funerary monuments along the via Latina further confirms the evolution of funerary uses also in _Aquinum_, which in the Imperial period, led to distinctions within necropolises based on wealth, with the survival of funerary areas for the burial of the less wealthy and the definition of a monumental road (via Latina) characterised by the presence of the tomb of the wealthier classes.
