Many have written of imperial qualities perceived or publicized, particularly of those attached to the emperor Constantine. Although only a tediously exhaustive volume could do justice to the whole subject, and any essay which does not embrace the whole runs the risk of being faulted for some omission or other, one may yet justify a particular concern. The subject of the present paper is the tension between form and function, which appears nowhere so readily as in a series of similar (...) literary exercises spanning a number of years, and the demonstration that form will always yield to practical necessity. For example, the rise, fall, and rehabilitation of Maximian through seven of the Panegyrici Latini clearly illustrates the many functions of a standard form. Constantine's is a more complicated case which involves two kinds of form and a certain amount of Augustan posturing. (shrink)
