MS Ege 4 is one of the many manuscripts that the infamous biblioclast Otto Ege dismembered for his manuscript portfolios. One of its leaves resides at the University of Saskatchewan as a part of Otto Ege’s manuscript portfolio Fifty Original Leaves from Medieval Manuscripts. This manuscript contains a unique compilation of commentaries on the Psalms by Philip the Chancellor and John Halgren of Abbeville and an alphabetical index. A careful analysis of MS Ege 4’s text, textual features, physical features, and research tools (medieval information technologies), which was made possible by means of a virtual reconstruction of this manuscript using available fragments, suggests that this manuscript was a preacher’s handbook. It was used by a preacher to compose sermons using Philip the Chancellor’s commentaries on the Psalter as a preaching aid via the alphabetical index. This study highlights not only the widespread use of Philip’s commentaries on the Psalter as a preaching aid, but it also addresses the role of individual preachers in the creation and dissemination of preaching aids alongside the professional reference tool makers.application/pdfMS Ege 4manuscriptsmanuscript studiesfragmentologysermon studiespreachingpreachersOtto Egereference toolsresearch toolspreaching aidsbiblical commentariesPhilip the ChancellorJohn Halgren of AbbevilleOtto Ege's Fifty Original Leaves PortfoliosThesis2021-06-10
