Ancient art is typically studied in terms of its aesthetic or historical value. This article presents an alternative approach, examining ancient Egyptian wall reliefs from a chaîne opératoire perspective. The reliefs assessed here adorn the walls of the Chapel of Hatshepsut at Deir el-Bahari in Thebes. The analysis reveals, for the first time, the sequence of the artists’ work, from the initial preparation of the wall surface to the master sculptor's final touches. This enables a reconstruction of the ergonomic organisation of the work, distinguishing the contributions of individual hands and revealing often intangible phenomena, such as master-apprentice interactions. A similar approach may be useful when examining carved reliefs in other parts of the world.
