It’s certainly true that Latin verse does things that Greek doesn’t, especially in hexameter and elegiacs. The “golden line” in hexameter is a prime example (adj.1 adj.2 verb noun-1 noun-2, e.g. irrita ventosae linquens promissa procellae, of Theseus’ abandonment of Ariadne on Naxos). The fashion seems to have been started by Catullus, in his mini-epic, Cat.64. You’d never find such a mannered word order in prose; it’s meter-dependent. Catullus overtly championed the “new poetics” associated above all with Callimachus, and Cat.64 is thoroughly and flamboyantly “Alexandrian” (aka Hellenistic) in all aspects, from the treatment of the story to features of language and meter. I reckon the fancy word order exemplified in Catullus’ poem and emulated to differing degrees by his Augustan successors was originally a development from Hellenistic poetry. Another forerunner of a kind is an elegiac poem by Hermesianax (another “Alexandrian” poet admired by the Augustans) that I quoted in an earlier thread (http://discourse.textkit.com/t/internal-rhyme-in-elegiac-couplet/15308/4), ostentatiously showing a pattern in the pentameter of adj. … noun distributed at caesura and line-end respectively. But Catullus and the Augustans appear to have developed these mannerisms still further.
