The buildings devoted to hospitality are divided into three groups, - one for the reception of distinguished guests, another for monks visiting the monastery, a third for poor travellers and pilgrims. The first and third are placed to the right and left of the common entrance of the monastery, - the hospitium for distinguished guests being placed on the north side of the church, not far from the abbot's house; that for the poor on the south side next to the farm buildings.
York was a Roman station (see below), and large collections of Roman remains are preserved in the hospitium of St Mary's Abbey.
Other views of the original aerarii are that they were: - artisans and freedmen (Niebuhr); inhabitants of towns united with Rome by a hospitium publicum, who had become domiciled on Roman territory (Lange); only a class of degraded citizens, including neither the cives sine sufJragio nor the artisans (Madvig); identical with the capite censi of the Servian constitution (Belot, Greenidge).
The Merveille (1203-1264) consists of two continuous buildings of three storeys, that on the east containing, one above the other, the hospitium (aumonerie), refectory and dormitory, that on the west the cellar, knights' hall (salle des chevaliers) and cloister.
These consisted partly in the general respect and esteem paid to a proxenus, and partly in many more substantial honours conferred by special decree of the state whose representative he was, such as freedom from taxation and public burdens, the right of acquiring property in Attica, admission to the senate and popular assemblies, and perhaps even full citizenship. Public hospitium seems also to have existed among the Italian races; but the circumstances of their history prevented it from becoming so important as in Greece.
Near the gate to the south was the guest-hall or hospitium (T).
These have been identified either with the hospitium or with the abbot's house, but they occupy the position in which the infirmary is more usually found.
