MS 125 contains sixteenth-century copies of Apologia and Appellatio contra capitulum Coloniense by Hermann von Wied, Archbishop of Cologne (d. 1551) and Martin Bucer's Constans defensio. The entire volume is probably in the hand of Martin Brem, Bucer's amanuensis, who also added a dedication to Matthew Parker. Martin Bucer (1491-1551) was a German Reformation theologian who moved to England in 1549 as a result of Archbishop Cranmer's invitation and Bucer's refusal to accept the Augsburg Interim (the temporary agreement brokered between the Catholics and Protestants at the Diet of Augsburg in 1548). Hermann von Wied was Archbishop of Cologne from 1515 to 1546. Initially hostile to Luther and the reformers, he eventually became sympathetic to the reformers' cause and was forced to resign his archbishopric.
