Mosaic from the House of Amphitrite, Bulla Regia
'Bulla Regia' is a
Roman city, now in northwestern
Tunisia, near the modern city of
Jendouba. It is noted for its
Hadrianic-era semi-subterranean housing, a protection from the fierce heat and effects of the sun. Many of the
mosaic floors have been left ''in situ''; others may be seen at the Bardo Museum,
Tunis. There is also a small museum connected with the site.
The
Berber origins of Bulla Regia probably pre-dated its
Punic culture: imported Greek ceramics of the fourth century BCE have been found; it came under the
hegemony of
Carthage during the third century, when inscriptions reveal that the inhabitants venerated
Baal Hammon and buried their dead in urns, Punic style. A capital from a temple of
Tanit is preserved at the site's museum. Broadly speaking, it was part of the territory conquered for Rome in 203 BCE by
Scipio Africanus, but in 156 BCE it became the capital of the
Numidian client-kingdom of
Massinissa, who "recovered the lands of this ancestors", according to an inscription, and gave to the site its epithet ''Regia'' ("Royal"); later, one of his sons had a residence in the city. Under the Numidians, a regularized orthogonal grid street plan in the
Hellenistic manner
[1] was imposed on at least part of the earlier irregular system of alleys and ''
insulae'' (Thébaut). The Romans assumed direct control in 46 BCE, when
Julius Caesar organized the province of
Africa Nova and rewarded the (perhaps simply neutral) conduct of Bulla Regia in the Civil Wars by making it a free city. Under Hadrian, it was refounded as 'Colonia Aelia Hadriana Augusta Bulla Regia', giving its citizens full ''
Romanitas''.
Its small amphitheatre, the subject of a reproach in a sermon of
Augustine of Hippo, retains the crispness of its edges and steps because it lay buried until 1960-61. Its bishop remains to this day a
titular see, as '' Bullensium Regiorum'', in the
Roman Catholic Church.
In the unique ''
domus'' architecture developed in the city, a ground-level storey, open to the warming winter sun, stood above a subterranean level, built round a two-story
atrium. Open-bottomed terracotta bottle-shapes were built into vaulting. Water sprinkled on the floors brought the colors of the mosaics to life while they provided cooling by evaporation.
In the House of the Hunt, the
basilica, with an apse at its head, a transept and dependent spaces opening into what would be the
nave if it were a church, has been instanced (Thébert) as an example of the conjunction between public architecture and the ''
domus'' of the ruling class in the fourth century, spaces soon to be
Christianized as churches and cathedrals.
The subtle colors and shading and the modelling of three-dimensional forms of the finest mosaics at Bulla Regia are not surpassed by any in North Africa, where the Roman art of mosaic floors reached its fullest development. The mosaic of a
haloed
Amphitrite (House of Amphitrite) is often illustrated (''above, right'').
After its season of flourishing, Bulla Regia was slowly degraded under
Byzantine rule. As elsewhere in the Late Empire, the local aristocracy found themselves in a position to increase the extent of their houses at the expense of public space: the House of the Fisherman was adapted to link two separate ''insulae'' turning a thoroughfare into a dead end.
Finally an earthquake destroyed Bulla Regia, collapsing its first floors into the subterranean floors. Drifting sand protected the abandoned sites, which were forgotten until the first excavations were begun, in 1906, in part spurred by the destruction of the monumental entrance to the Roman city. The forum, surrounded by porticoes, was excavated in 1949-52. Its public
basilica had an
apse at each end. As a cathedral it had a highly unusual cruciform baptismal font inserted the center of the rear (west end) of its nave (Jensen).
