Nasca geoglyphs: Technical aspects and overview of studies and interpretations

Abstract

Archaeologists and scholars have long debated the purpose of the Nasca lines. During the last two decades, significant advances in the understanding of cultural and functional aspects of geoglyphs have been achieved. This chapter deals with the state of the art of studies, research, and field activities in various areas of the Nasca territory. In particular, the technical aspects related to the execution of the geoglyphs and dating issues are discussed. The chapter ends with reprise of the debate on the functions and significance of the Nasca lines from the Spaniard chroniclers to the most recent investigations, oscillating from calendrical/astronomical theories to approaches closer to the Andean model.
