This portrait of a beautiful young woman, crowned with flowers as if on her day of investiture into religious orders of the Catholic church, carries with it a great deal of information, yet all the "hard" evidence only adds to the essential mystery and charm of the image. The central inscription identifies the sitter as the Reverend Mother Maria Antonia de Rivera, who took her vows as a nun on December 12, 1757. It is painted over, and partially obscures, an earlier inscription that records that she was elected prioress in 1791 and died in 1806. Is it, on first guess, a kindly evocation of woman's youth, done after she had achieved high rank and power? Or was her status such that her portrait was painted upon entry into the convent and her deeds only inscribed later, perhaps even after her death? Or, a most happy speculation, was each new nun portrayed at this level of refinement, with this painting being a rare survivor of some late nineteenth-century sacking of the convent in one of the numerous anticlerical movements that swept Mexico?
