Each of the three major anthologies from which Cephalas took epigrams had its own introductory poem; these have been grouped together in Book 4.
Meleager’s poem (4.1) uses the metaphor of a garland to describe the authors from which he took epigrams.
Philip’s much shorter poem (4.2) adopts this metaphor, but much more simply.
Agathias wrote a compound introduction, which is variously numbered in published editions. I have elected here to break it up into three poems (4.3–5), along the lines of its three metrically differentiated parts—iambic trimeter, dactylic hexameter, and elegiac couplets.
