Johannes Oecolampadius

Johannes Oecolampadius, IPA: [ɔɪkɑːlæmpædiːʌs], or Oekolampad (1482 – 24 November 1531) was a German Reformed theologian religious reformer from the Electorate of the Palatinate. He worked with Erasmus and Zwingli, and also influenced a later generation of Protestants, including Heinrich Bullinger and John Calvin. Theologically he was considered to be close to Zwingli, with whom he shared a friendly attitude towards Mary and Marian veneration.

His real name was Hussgen or Heussgen, a name first changed to Hausschein and then into the Greek equivalent, which is derived from oiko-, "house," and lampad-, "lamp".

He was born in Weinsberg, then part of the Electorate of the Palatinate. He attended school at Weinsberg and Heilbronn, and then, intending to study law, he went to Bologna, but soon returned to Heidelberg and took up theology. Enthusiastic about the new learning, he passed from the study of Greek to that of Hebrew, taking his bachelor's degree in 1503. He became cathedral preacher at Basel in 1515, serving under Christoph von Utenheim, the humanist bishop of Basel. In Basel, Oecolampadius became an editorial assistant and Hebrew consultant to Erasmus' first edition of the Greek New Testament, and wrote that edition's epilogue in praise of his master.
