Un contexto funerario, excavado en 1982, en el sitio de Armatambo proporciona la base para describir el estilo de textiles Ychsma durante el Horizonte Tardío.

La procedencia de los textiles Ychsma en las colecciones de los museos, es considerada para sugerir el ámbito de interacción de la cultura Ychsma en la costa central.

The visual axis 1 is related to another alignment (visual axis 2) that crosses the center of the square frame of the third platform, and links the top of mound El Mirador to th...
