History and context

Subterranean galleries captured fossil water and conducted it by gravity towards the oases. Aligned wells allowed excavation, sediment removal and maintenance of the work.

A recent synthesis records more than 2,000 km of networks in Fezzan and about 100 km² of relict fields. Technological origin and earliest dates remain under discussion.

The aligned wells made it possible to dig, ventilate and clean galleries of minimal slope. Water flowed by gravity and its maintenance continued while the system functioned.

The regional synthesis calculates more than two thousand kilometres of networks. That aggregate magnitude does not prove a single state project or a single labour regime.

Evidence and interpretation

Layout, inventories, fields and use chronology are published. Inventor, labour regime and political control are not known uniformly.

A brick helps date the water

At al-Hatiya, organic matter contained in the mudbrick lining of a foggara shaft was analysed. The published dating gives a range of 391–206 BCE for that material. It is an example of how a gallery that is difficult to date can be linked to a specific sample from its construction. The relationship between brick, shaft and channel matters: it allows an alignment visible in the landscape to be turned into chronological evidence. The result dates that element of the system, without requiring all nearby galleries to have the same date.
