The Blue Nile Falls: Ethiopia's Ancient Waterworks
Description
We trace the little-known story of Ethiopia's ancient hydraulic engineering along the Blue Nile, from 1st-century Aksumite dams at Lake Tana to the medieval stone channels feeding Lalibela's rock-hewn churches. Lucas explains how Aksumite kings built reservoirs to control the Blue Nile's floodwaters, extending their reach into Sudan, and how later emperors like Susenyos and Fasilides dug canals that still irrigate the Gonder region. We examine the mysterious 'Stone of the Nile' – a giant carved monolith that may have been a nilometer – and the 16th-century Ottoman attempt to divert the river. Luna asks about the role of the Ethiopian Orthodox Church in preserving these water systems, and Lucas reveals how recent archaeology uncovered a 2,000-year-old water-lifting device called a 'shaduf' still in use today. The episode ends with a reflection on how Ethiopia's ancient water management shaped its unique identity as an African superpower.
