This publication is the latest monographic outcome of a long-term project of survey and research of the archaeological site of Abusir, focusing on a particular set of cemeteries located at Abusir South. The present volume of the Abusir series concentrates on the mastaba of Neferinpu (AS 37). It aims to present primary data and their basic analysis and interpretation acquired during the tomb examination by the Czech Institute of Egyptology during two subsequent seasons of 2006 and 2007 and followed by some minor campaigns in 2012 and 2013 and a specific analytical campaign in September 2014 carried out by the Japanese team from Tokyo University of Science. The mastaba was built by a sun priest and official Neferinpu who reached the peak of his career during the reign of Nyuserra and Djedkara.
