Ivan Ratkaj

Croatian Jesuit missionary and explorer (1647-1683)

Izvješća iz Tarahumare, a detailed account penned by a seventeenth-century missionary, serves as the primary record documenting the customs and geographic landscape of the Tarahumara people. This narrative represents a significant contribution to the early ethnographic documentation of North America, bridging the observational traditions of a Jesuit traveler with the evolving cartographic standards of the Holy Roman Empire.

Ecclesiastical Formation and Departure

Born in 1647 in Ptuj, then part of the Duchy of Styria, Ivan Ratkaj descended from the Ratkaj noble family, who held the title of barons of Veliki Tabor. He entered the Society of Jesus in 1664, pursuing rigorous academic training in philosophy and theology within Graz. Before embarking on his overseas mission, he served as an instructor of Latin at educational institutions in Gorizia and Zagreb. Although his superiors initially favored a continued career in pedagogy, he secured permission to travel to Mexico as a missionary, arriving at the port of Veracruz in September 1680.

Exploration of the Tarahumara Region

Following his arrival in Mexico, Ratkaj traveled north to the Tarahumara province, located in the territory of present-day Chihuahua. He established himself at the mission in Tutuaca, situated in a mountainous environment. During this period, he produced a formal map of the region, meticulously marking the locations of established Spanish forts and missionary outposts. His writings combined a diary format with objective ethnographic observation, recording the daily habits, language, and cultural practices of the indigenous population.

Documentation and Final Years

Ratkaj displayed proficiency in the local language, reportedly mastering it within a single month of interaction. His reports characterize the Tarahumara as a civilized group, though he simultaneously noted their propensity for magic. He documented his mission of proselytization, actively attempting to influence local social behaviors. His tenure was brief; he died in 1683 in Carichí at the age of 36. While historical speculation suggests he may have consumed poisoned water, contemporary accounts from the period do not provide verification for this claim.
