Durango. The Poor Clares of Durango belonged to the rule of the third penitential order of San Francisco from 1439 to 1610. In the manuscript Monumenta ordinis preserved in the library of the convent, an important testimony of the language has been found because it is prior to 1521. It deals with the Basque formula for profession of the third order: "I am from such a place of my own free will and I vow & promise to Almighty God and to the blessed Virgin Sancta Maria and to the blessed Sat Fr(ancisco) and to all the saints and saints of the court of Heaven, to you, father, to guard all the time of my life the third rule of Sat Fr(ancisco) of the brothers and sisters, said of penance, by the Lord Pope Nicolao fourth given and granted , by Pope Sixtus, fourthly cosigned and approved, living in ob(edience)ia without proper and in chastity.-Dicat recipies: Si hoc obseruabis, ego promitto tibi vitam eternam."Ni N. neure borodate gustirean voto egitedot eta promitietadot / Jaingoicoari ta Andradone M(aria) virgineari eta Sat Fra(nci)scuari eta / cerucu sanctu eta sancta custiaj ta uri aita goardaetaco erreguela / third Sat Fraciscuare ordeacoa penitenciacoa ayta sanctu Nicolao / laugarrenare emona eta concedadua eta ayta satu sist lau / garrenare approved ta cofirmadua, bi i izaiteco obey ian / eta poor an eta castidadean. / Au guardadu badagui u, nic prometeta deusut gure Jaunare / rregnua.
