Stratigraphy
Three cultural phases which preceded the Chavin culture were identified at Kotosh,
Kotosh
Wairajirca
Mito
Kotosh Period
The Kotosh Period culture stratum was situated directly beneath the Chavin culture stratum.
At this stage, maize cultivation has appeared.
Some Kotosh elements show links with the Chavin culture. For example; stirrup spouts, plain rocker stampings, and curvilinear ceramic designs. There are also similarities in black paint on red ceramics. Kotosh Black Polished Incised pottery is similar to Classical Chavin pottery.
Wairajirca period
This is when the first pottery appeared.
Wayrajirca pottery was originally found at its type site Wayrajirca, which is near Kotosh, and this pottery is also known from elsewhere in the northern highlands. The Wairajirca period continued from the late eighteenth to late twelfth century cal BC (1750-1150 BC).
The pottery is characterized by the polished brown and black styles decorated with incisions and post-firing paint. The designs are simple and geometric; anthropomorphic figures be added at later periods.
The Kotosh Period strongly maintained the traditions of the preceding Wairajirca Period, including the ceramic tradition.
Kanezaki (2021) investigated the Jancao site in the Department of Huánuco of Peru, which is also near the Kotosh site. In the neighborhood, there are also other important archaeological sites of the Formative period, such as Wairajirca and Shillacoto. According to Kanezaki, the Kotosh and Shillacoto sites were no longer occupied at the end of their preceramic phase before their Wairajirca ceramic phase started. But they were reoccupied again during the Phase III of Wairajirca chronology (1400-1500 BC).
Mito period
Terracota "Crossed arms" from Kotosh, 1800 BC
This was the earliest identified cultural period, which was preceramic. During this period, The Temple of the Crossed Hands was first built. The image of crossed arms is characteristic for the Kotosh temple iconography.
