This book presents the hieroglyphic documentation of the site of Bab el-Maganin, located in the town of Armant, south of Luxor. An enclosure gate built by Antoninus Pius (138-161 AD) bears witness to a secondary cultic domain, buried under the modern houses nearly 300 meters from the main temple dedicated to the god Montu-Re. Around it lie dozens of inscribed blocks. These sets of stones were partially published in 1940 by Robert Mond and Oliver Humphrys Myers, then by Adel Farid in 1979. The work resumed at Armant under the auspices of the IFAO has gradually allowed to bring together all of this scattered documentation, which the archives of the Egypt Exploration Society in London have significantly enriched. Amongst this heterogeneous epigraphic material, it is possible to virtually reconstruct part of a monumental gate bearing the names of Ptolemy VI Philometor, Ptolemy VIII Euergetes II and Ptolemy IX Philometor II. Despite their fragmentary nature, these inscriptions provide important information about the cults of the god Montu-Re and his relatives in the Theban area during the Graeco-Roman period.
