The literary epigram is one of the most versatile ancient literary genres, and epigrammatists have often used it as a testing ground for the recollection and construction of their literary past. This chapter compares the corpus of Decimus Magnus Ausonius and Palladas of Alexandria, two eminent representatives of the epigrammatic genre from the later imperial period. Ausonius’ dialogue with the literary past is characterised by a discourse about the value, validity and reliability of classical authors and authorities from the Greek and the Roman world. For this purpose, Ausonius uses various techniques such as the juxtaposition of acknowledged and anonymous sources, the inclusion of ‘fake sources’, and a recurring discussion of Greek versus Roman authorities. In contrast, Palladas constructs a persona of himself which resorts to Greek authorities only and, especially, to Homer. Palladas appropriates Homer and the Homeric epics in order to construct his personal voice, whereas the actual discourse about classical authors and authorities remains comparatively flat and limited as compared to Ausonius.
