The town of Djenne on the Bani River in Mali has been a thriving settlement for more than two millennia. Renowned for its mud-brick architecture, monumental mosque, and merchant-traders’ houses, Djenne remains one of Africa’s most distinctive cities. The Masons of Djenne follows Trevor Marchand after he signs on as a builder’s apprentice. Marchand takes readers on his journey from raw laborer to skilled craftsman. He explores the professional associations of masons, their social networks, training regimes, and changing fortunes. With his fellow builders, he produces mud bricks and plasters, constructs walls and ceilings, and sculpts rooftop crenellations using specialized tools. Marchand describes the raising of a mud-brick house and explores the technical, social, and magical processes involved in making buildings and renewing the unique urban environment of Djenne.
