ABSTRACT
This introduction presents an overview of key concepts discussed in the subsequent chapters of this book. The book contains the largest number of donors listed in a single medieval Strasbourg obituary; at first glance the pages appear surprisingly empty. The format of the Book of Donors displays a pair of lined pages for each calendar day of the year, with the day in red letters on the verso side and the page number in black Roman letters on the top center recto side. The Mullenheim family was prominent among the nobility of Strasbourg, as prominent as the Zorn clan, their chief rivals. Among the Mullenheim family members listed in this book are no less than 13 entries bearing the name Heinricus Mullenheim. The layout of the book remains consistent throughout, with one major exception in the addition of two bifolia sewn into the book about the year 1460.
