An eminent German reformer, born, in 1482, at Weinsberg in Franconia. He was converted to the Protestant faith by reading the works of Luther; became professor of theology at Basle; embraced the opinions of Zuinglius respecting the sacrament; contributed much to the progress of ecclesiastical reform, and died in 1531.

Œcolampadius was of a meek and quiet disposition; in the undertaking of any business he was very circumspect; nor was there any thing more pleasing to him, than to spend his time in reading and commenting. His publications are numerous, consisting chiefly of annotations on the holy Scriptures.
