A Diplomacy of Gender: Rituals of First Contact in the "Land of the Tejas"

Nearly sixty years later, in 1689, when Spaniards sought permanent settlement in the "land of the Tejas," along the Red River region of the present-day Texas-Louisiana border, they recalled stories of Ágreda's prior visitations and sought evidence that might serve as a touchstone for beginning their own missionary efforts.2 Much to the delight of fray Damián Mazanet, Caddo Indians of the Hasinai confederacy (known to Spaniards as "Tejas" Indians) responded positively to his queries. Yes, he understood them to say, a mysterious "Woman in Blue" had appeared among them, not in living memory, as one caddí (the Caddo term for a chief or cacique) attested, but according to stories told by grandparents.3

(from another source)
One such story is that of the apparition of María de Jesús Coronel, Sor María de Agreda. Fray Damián Manzanet had specifically been given instructions to look for the tribes that Sor María de Agreda had visited in her religious ecstasy. The Franciscan found the tribes in Texas, and
. . . Manzanet and his companions were joyfully and kindly received and shown every consideration. The Governor, or Chief, of the Tejas Indians one day asked Manzanet for some blue baize in which to bury his grandmother when she died.
Manzanet asked him why he desired it blue. The Chief replied that it was because a beautiful woman who had come often to visit their tribe and whom they reverenced wore blue, and they wished to be like her on passing to the other world … she had promised them teachers, and now that Manzanet and his companions had come, the "high priest" or medicine man of the tribe had told them that these were the true teachers who had been expected.
The strange part of the story is that Mary de Agreda had never really been in Texas or the New World in person, but during her state of intense longing and continued prayer, she must have dreamt or visited them in ecstasy…. She conversed with these dream people and promised them teachers which she finally caused to be sent as we have seen. Numerous were her writings descriptive of these people, their country, customs, and names of tribes, and it was afterwards found to be correct and true. (de Zavala 101-102)

This is a Caddo connection.
