Claude Chauchetière, Catherine Thegakouita
St. Francis Xavier Church, Kahnawake, Quebec
Chauchetière was the saint's spiritual director. Catherine Thegakouita is the spelling he used when he wrote her biography. Today it is usually spelled Kateri Tekakwitha.
The painting hangs in the church in Kahnawake. Their website ascribes it to Chauchetière and dates it as circa 1690, which would be ten years after St. Kateri's death. The church in the background seems too grand for this early period in Quebec history, though it does resemble the more modest Notre-Dame des Victoires, built in 1687 in Quebec City.
In any case, the painting can be thought of as the source of several features of subsequent iconography: the laced footware, the short, fringed mantle common among the Mohawk, and the cross. However, most later images leave out the blanket-like mantle.
