This paper presents an archaeological report on the anonymous Fifth Dynasty mastaba AS 88 from the Abusir South necropolis, south west of the tomb of the official Kaaper (AS 1). The tomb was reduced to the ground in antiquity and only fundaments of its architectural disposition remain: the chapel and serdab located in the southernmost third of the ground plan, and the main burial Shaft 4 with looted burial chamber to the north. The tomb owner was a robust male who lived to relatively old age, between 40 and 60 years. Neighbouring ritual Shaft 5 has been undisturbed since antiquity and near its opening, a dislocated base of a combed ware vessel of Syro Palestinian provenance was found, probably having come from the looted burial equipment of Kaaper. Other selected ceramic, anthropological (including two undisturbed Old Kingdom burials in subsidiary shafts of the tomb), and archaeozoological finds are presented as well in the report. The last part of the article discusses the importance of similar structures in the broader understanding of the Old Kingdom at Abusir, as they provide a humble counterpart to the pyramids and major tombs of Royal Abusir.
