Wołoszyn * * University of Warsaw, Poland suMMary This paper concerns the research done in the framework of the Toro Muerto Archaeological Research Project (TMARP) that has resulted in registration of 1,664 boulders covered with petroglyphs, probably made by the representatives of the several cultural traditions developing in this region of Peru, from about the middle of the first millennium to the middle of the second millennium AD. The individual decorated panels of some of the larger boulders are frequently covered with dozens of various representations made using various techniques. They include geometric motifs, zoomorphic and anthropomorphic representations. The documentation works were carried with the use of both traditional and modern technics used in archaeology. riassunTo L’articolo affronta la ricerca condotta all’interno del progetto Toro Muerto (TMARP) che ha permesso di classificare 1664 rocce incise da popoli diversi che hanno abitato il Perù fra il 500 e il 1500 d.C. I pannelli individuali sono spesso decorati con decine di raffigurazioni realizzate con tecniche diverse. I soggetti più rappresentati sono: motivi geometrici, zoomorfi e antropomorfi. Il lavoro di documentazione è stato eseguito utilizzando sia tecniche archeologiche tradizionali che moderne. In 2015 and 2016, a group of Polish researchers from the Institute of Archaeol- ogy of the University of Warsaw conducted two bi-monthly feld works in Toro Muerto, an exceptionally complex rock art site in southern Peru. The research done in the framework of the Toro Muerto Archaeological Research Project (TMARP) has resulted in registration of approx. 3.5 km² area with 1,664 boulders covered with petroglyphs. The research revealed also new features of the site, which had either not been noticed by earlier researchers or considered in earlier analyses. This work was made possible by the funding from the Polish Ministry of Science and Higher Education (Diamond Grant No. DI 2013008843) and the help of the local authorities, represented by Ramón Zegarra Prado - mayor of the Uraca- Corire District. The main objective of the project was to elaborate documenta- tion methods, which could be most useful for documenting large-scale rock art sites. Karolina Juszczyk was the TMARP Manager, its director from the Peruvian Ministry of Culture was Abraham Imbertis Herrera and the academic supervisor was Janusz Z. Wołoszyn. The Toro Muerto site is located in the central part of the Majes Valley near Corire (Uraca-Corire District, Province of Castilla, Region of Arequipa). It is ap- proximately 4 km from the river as the crow fies, situated on a hilly, desert area west of the foothills of the Andes at altitudes ranging from approx. 500 to 1200 meters above sea level. The area of the site is covered by exceptionally numerous randomly scattered boulders of volcanic origin of between several dozen centi-
