Running Rhythm is common to English, whereas Sprung Rhythm is?

Note on the nature and history of Sprung Rhythm— Sprung Rhythm is the most natural of things. For (1) it is the rhythm of common speech and of written prose, when rhythm is perceived in them. (2) It is the rhythm of all but the most monotonously regular music, so that in the words of choruses and refrains and in songs written closely to music it arises. (3) It is found in nursery rhymes, weather saws, and so on; because, however, these may have been once made in running rhythm, the terminations having dropped off by the change of language, the stresses come together and so the rhythm is sprung. (4) It arises in common (6) verse when reversed or counterpointed, for the same reason. But nevertheless in spite of all this and though Greek and Latin lyric verse, which is well known, and the old English verse seen in Pierce Ploughman are in sprung rhythm, it has, in fact, ceased to be used since the Elizabethan age, Greene is the last writer who can be said to have recognized it. For perhaps there was not, down to our days, a single, even short, poem in English in which sprung rhythm is employed not for single effects or in fixed places but as the governing principle of the scansion. I say this because the contrary has been asserted: if it is otherwise the poem should be cited.

All to the same scansion unit, or so it would seem. 365 degrees in all yet sixty seconds completes the möbius. The heroic hexameter... Homer's Iliad and Odyssey, Virgil's Aeneid, and Ovid's Metamorphoses were all composed in Dactylic Hexameter.
