Since Bury's magistral article in this Journal over thirty years ago (XIII, 1923, 127 ff.) no scholar has attempted a comprehensive study of the date and value of the Laterculus Veronensis. Various historians have in passing expressed a preference for this date or that. Ernst Stein argued for 293–305 in Rheinisches Museum LXXVII (1925), 367, but in his Geschichte des spätrömischen Reiches 1, 102, preferred 304–306. E. Schwartz in a rathe fuller treatment (Abh. Bayer. Akad., phil.-hist. Kl., 1937, 79–82) argued for a much later date, between 325 and 337 for the eastern dioceses, and under Valentinian I for the western dioceses. Others have more modestly confined themselves to certain areas. H. Nesselhauf has maintained a relatively early date (305–306) for Gaul (Abh. Preuss. Akad., phil.-hist. Kl., 1938, 8 ff.), while W. Seston has argued for a date after 306 for Africa (Dioclétien et la Tétrarchie, I, 327–8). It may be timely to reassess the problem, particularly as some new evidence has recently emerged.
