We are both immensely pleased to have played supporting roles in the
archaeological research that led to this volume. As a faculty member at
the Universidad del Centro (Huancayo) in the 1960s and later at the
Universidad Nacional de San Marcos (Lima), Matos Mendieta developed a
special interest in the Upper Mantaro and adjacent Tarma drainages, and
during the 1960s and 1970s, he carried out general reconnaissance and
several excavations in the area between Lake Junín and Huancayo. Matos
Mendieta began his field research in the Sierra Central as part of the
"Proyecto Andino de Estudios Arqueológicos" sponsored by the Smithsonian
Institution. As a fellow at the Smithsonian Institution in the
mid-1960s, Matos Mendieta began to interact more closely with North
American scholars; during this period, he began to encourage and
facilitate the interests of several US. -based archaeologists in the
Peruvian Sierra Central, including Craig Morris, John Murra, and Donald
Thompson, who were beginning fieldwork at and around the Inka provincial
center of Huanuco Pampa north of Lake Junín, and David Browman, who in
1969 carried out one of the very first systematic archaeological surveys
in highland Peru over parts of the main Mantaro Valley between Huancayo
and Jauja.
