Aggenus Urbicus
Aggenus Urbicus (also Agennius Urbicus) was an ancient Roman technical writer appearing in the Corpus Agrimensorum Romanorum, a collection of works on land surveying from Late Antiquity. It is uncertain when he lived, but he may have been a Christian living in the later part of the 4th century, judging by expressions he uses.
Only two, fragmentary works are preserved in the Corpus Agrimensorum Romanorum under his name:
- De controversiis agrorum ("On Land Disputes")
- Commentum de agrorum qualitate ("Commentary on Land Quality"), a commentary on the work of this name by Frontinus.
- The Liber Diazographus ("Multi-coloured Painter Book") attached to the Commentum is sometimes counted as a third work.
