Balbín’s treatise from 1665 deals with Svatá Hora (‚Holy Mountain‘), the place of pilgrimage near Příbram, where the local Jesuits fostered and spread the Marian cult. Since both Balbín and Šteyer highlight Virgin Mary as a protector and miraculous healer of children, our analysis is focused on first names of the miraculously cured children. The paper examines the origin and frequency of these names; the influence of a child’s social class and tradition on the choice of the name; the influence of the then promoted names of Baroque saints (e.g. František, Marie, etc.); the practice of giving children one or two Christian names. As a result of Christian influence, the most frequent names at the time were biblical names and the names of saints (Jan, Václav, Anna, Kateřina, Lidmila). These include the names of Czech patron saints. The „Baroque“ names, advocated by the Catholic church, were, however, slow to penetrate into the repertory of first names. It was not until the early 18th century that they began to achieve widespread popularity.
