Olearius, Johann—whose real name was Oelschläger—1611-1684—of Halle, chaplain to the king and superintendent-general at Weissenfels, a learned theologian. His numerous hymns stamp him as the Gellert of his time. With true scriptural singleness of heart, an ardent Christian mind, and great abilities, he endeavoured to restore the sublime simplicity of the church-hymns, and to put fresh vigour into their style. This gave him, as it did Gellert eighty-six years later, a great influence over the hymn-books, in which many of his writings were soon adopted.
