Millcayac

Millcayac was a Huarpe language spoken around Mendoza and in lands to its south. Its speakers lived east of the Andes, where river water sustained agriculture in an otherwise dry region. The Jesuit Luis de Valdivia published a grammar, vocabulary and religious texts in Millcayac in 1607, seeking to assist missionary work among Huarpe people. Many had been taken across the mountains to work in Chile under Spanish rule.
