This is the first edition of the fourteenthcentury Lumen anime C and of its German translation Das liecht der sel completed in 1426 by Ulrich Putsch Bishop of Brixen Bressanone in the South Tyrol. The two works are theological compendia for use in homiletic and catechetical contexts and teach their intended readership much about basic Christian doctrine and morality with a special emphasis on the Virgin Mary. Their didactic method makes particular use of nature exempla and of frequently spurious quotations from authorities. Both were highly influential in latemedieval Germany especially in Austria and Bavaria but their important role in conveying the insights of latemedieval Catholicism to an increasingly numerous lay audience has yet to be fully appreciated. The present edition should facilitate this and several other necessary reassessments. Critical texts of the Latin and German versions are printed in parallel. They are preceded by an introduction which offers for each text in turn descriptions of its manuscripts an account of its textual history and an evaluation of previous research and in respect of Das liecht der sel also covers the biography of Ulrich Putsch.
