"The all-inclusiveness of the RV in the realm of mythology is also observable in the sphere of poetics. There is hardly a major poetic device in the various IE branches that is not present in the RV. A significant aspect, for example, is that in early Greek poetry (epics of Homer and Hesiod, and some epigraphic material) the fairly strict syllabic meter (the hexameter with its dactylic, iambic and other variants) is preponderant with only traces of alliteration; in Germanic poetry alliteration prevails while the syllabic meter is very loose: both are present in the RV. ...Early Irish poetry (6th century CE) has both meter and alliteration (and rhyme) but this hardly counts since the Irish poets knew these poetic devices “from Vergil and Ovid” and, of course, the Romans developed them from the Greek tradition."
