The chronology of Machupicchu was traditionally associated with the period attributed to the reign of Pachacuti Inca Yupanqui. Within the scheme on the so-called historical chronology, proposed by John H. Rowe in 1945, the ascension to power of Pachacuti Inca took place around 1438 AD and the construction of Machupicchu began by 1450 – 1460 AD. There are several radiocarbon-dated samples that may help to try to understand the chronology of the construction of llaqta of Machupicchu, Chachabamba, and Choqesuysuy. The sites have been interpreted as being part of the contemporary Late Horizon Inca landscape. However, all the sites are located in the Andes where the influence of the Northern and Southern Hemisphere for the atmospheric radiocarbon radioactivity is to be investigated and discussed for different periods. The influence will probably reflect both regional and global climatic changes in the region. Here we present how different mixing of Intcal13/SHcal13 and Intcal20/SHcal20 radiocarbon calibration curves influences the chronology of all three sites.


Biography:

My scientific career started in the year 1993; since then, I have been employed in the Institute
of Physics (Division of Radioisotopes) at Silesian University of Technology (SUT) in Gliwice.
Between 1995 and 1999, I undertook my doctoral study in SUT, receiving in 1999 the degree
of Doctor of Sciences in Physics.
