The Islamic site of Nora, in what is now the district of Ifat in Ethiopia, is located on a rocky spur halfway up the slope of the Rift escarpment. It was abandoned several centuries ago, and reveals the vestiges of an Islamic town that was inhabited from the end of the 13th century to the first third of the 16th. This book describes the results of an excavation carried out in Nora in 2008. It presents the information and interpretations gathered from excavations of a number of domestic residences, two of the five mosques found on the site (including the Great Mosque) and a tomb in a silo. The ceramic, glass and metal artefacts, and a sample of faunal remains are also described. As well as offering observations that make it possible to place the Islamic site of Nora in its particular geological and agrarian landscape, the book dedicates particular attention to geoarchaeological information regarding the settlement and formation of the site, a stratigraphic interpretation of the phases of settlement and abandonment and an architectural description of the buildings.It is proposed that Nora be identified as the locality of Tobyā, which is one of the towns of the sultanate of Afwāt (in Arabic) or Ifāt (in Geez) mentioned in written sources. It is the first Islamic site to have been extensively excavated in Ethiopia.Edited by François Xavier Fauvelle & Romain Mensan, with contributions by Laurent Bruxelles, Chloé Capel, Amélie Chekroun, Deresse Ayenachew Woldetsadik, Samir El Ouaamari, Habtewold Habtemikael, Bertrand Hirsch, Clément Ménard, Bertrand Poissonnier, Stéphane Pradines, Guillaume Saint-Sever, Abigail Chipps Stone, Helina Solomon Woldekiros and Hailu Zeleke Woldetsadik (†).
