Book excerpt: As a result of The Metropolitan Museum of Art's renewed excavations in Lisht, the Egyptian Department published The Pyramid of Senwosret I by Dieter Arnold in 1988, followed in 1990 by The Control Notes and Team Marks by Felix Arnold. The first volume examined the main pyramid and its related mortuary installations, while this third volume, The Pyramid Complex of Senwosret I by Dieter Arnold, discusses the monuments and objects found within the outer enclosure wall of the royal pyramid, mainly the nine subsidiary pyramids and other tombs belonging to members of the royal family and their households. Although the pyramids and their surrounding installations are much destroyed and the burials pillaged, it has been possible to reconstruct, to some degree, the architecture from these ruins. Such a reconstruction is particularly important, as no other pyramid enclosures of the Middle Kingdom, and very few of the Old Kingdom, have ever been so thoroughly excavated and published. The results of this enterprise provide an important contribution to our understanding of the structure and development of the royal funerary complexes of the Middle Kingdom.
