Perhaps nowhere, however, had the “Roman peace” worked greater miracles of civic prosperity than in North Africa. That the population of Roman Africa was in the period of the Empire extraordinarily dense, appears from the number of its episcopal sees, which in the fifth century had reached a total of 297.(1148) The remains of more than 20 amphitheatres can still be traced. There is indeed no more startling proof of the range and sweep of Roman civilisation than the wreck of those capitols, forums, aqueducts, and temples in what are now sandy solitudes, not even occupied by a native village. In the province of Numidia, within a few leagues of the Sahara, the Roman colony of Thamugadi (Timgad) was founded, as an inscription tells, by Trajan in the year 100.(1149) There, in what is now a scene of utter loneliness and desolation, the remains of a busy and well-organised community have been brought to light by French explorers. The town was built by the third legion, which for generations, almost as a hereditary caste, protected Roman civilisation against the restless tribes of the desert. The chief buildings were probably completed in 117. The preservation of so much, after eighteen centuries, is a proof that the work was well and thoroughly done. The ruts of carriage wheels can still be seen in the main street, which is spanned by a triumphal arch, adorned with marble columns. Porticoes and colonnades gave shelter from the heat to the passers-by, and two fountains played at the further end. Water, which is now invisible on the spot, was then brought in channels from the hills, and distributed at a fixed rate among private houses.(1150) The forum was in the usual style, with raised side walks and porticoes, a basilica, a senate-house and rostrum, a shrine of Fortuna Augusta, and a crowd of statues to the emperors from M. Aurelius to Julian.(1151) This petty place had its theatre, where the seats can still be seen rising in their due gradation of rank. An imposing capitol, in which, as at home, the Roman Trinity, Jupiter, Juno, and Minerva, were duly worshipped, was restored in the reign of Valentinian I., and dedicated by that Publius Caeionius Albinus who was one of the last of the pagan aristocracy, and who figures in the Letters of Symmachus and the _Saturnalia_ of Macrobius.(1152) The inscriptions on the site reveal the regular municipal constitution, with the names of seventy decurions, each of whom probably paid his honorarium of £13 or more when he entered on his office.(1153) The honours of the duumvirate and the aedileship cost respectively £32 and £24.(1154) And here, as elsewhere, the public monuments and buildings were generally erected by private ambition or munificence. A statue and little shrine of Fortuna Augusta were given by two ladies, at a cost of over £200, in the days of Hadrian.(1155)
