William E. Metcalf is a prominent name in numismatics, but is also universally recognized among those who study Roman history and archaeology. Known especially for his many contributions to Roman and Byzantine coinage, it is difficult to find a book or article that does not cite his work. A generous scholar, one can see his name in the acknowledgments in works by numismatists and scholars in adjacent disciplines who incorporate numismatic evidence. It is thus appropriate- and overdue-that his former students and colleagues present this Festschrift in recognition of Metcalf 's impact on our discipline. It would be impossible to incorporate contributions from all of his colleagues and friends; the contributors herein represent but a fraction of those who would honor him.
