Ivan Ratkaj

Ivan Ratkaj (22 June 1647 – 26 December 1683), also Ivan Rattkay, was a Croatian Jesuit missionary, explorer and cartographer. He wrote the first detailed description of the Tarahumara, a Native Mexican people.

Ivan was born in Ptuj (Duchy of Styria, now northeastern Slovenia) to the Ratkaj noble family, barons of Veliki Tabor. After graduating from the Gymnasium, he joined the Society of Jesus. There he studied philosophy and theology. When he graduated, his superiors wanted him to teach, but they eventually granted his wish and sent him to be a missionary in Mexico in 1680.

In his reports, written in the form of a diary, Ratkaj described his sea voyage to Mexico, the land route to the native province of Tarahumara in the north of Mexico and the customs and life of the Tarahumara people. He also drew a map of the region with missions and Spanish forts.

Ratkaj provided the first ethnographic and geographic presentation of the Tarahumara. He learned the native language in a month and moved to Tutuaca, a mission in a poor mountainous area. His reports betray an open curiosity: he noted all kinds of details, not only of nature, but also of the natives and their life. He mostly tries to show the Tarahumara in an objective light. He presents the Tarahumara as a "mild and civilized" people as opposed to some neighboring tribes. But they are "fiercely addicted to magic" like other tribes. He describes his role as spreading God's name among the pagans. He also urged them to abstain from drinking and dissolution.

He died in Mexico.
