About Timgad (Thamugadi)
Exemplar Roman colonial grid city founded ex nihilo by Trajan c.100 CE for veterans of Third Augustan Legion, Timgad displays perfect castrum plan: square 355×250 m, decumanus and cardo crossing at forum, 14 baths, theatre (3,500), Capitol Jupiter temple 26 m high, library (scholar estimate), triumphal Arch of Trajan (later Dona...?). Later Byzantine fort over west quarter. Called 'African Pompeii'.

Mysteries & theories
Mysteries
- 01Library identification – argues as public library from inscription vs ordinary annex
- 02Why orthogonal grid extended less rigidly outside initial square – organic growth
Theories
- 01Trajanic foundation inscription specifies 'for veterans' indicates deliberate Romanisation policy
- 02Byzantine fort reoccupation after Vandal interlude shows continuity
Theories are interpretations, not findings. The seal above tells you how much scholarly weight the place carries.
