The written word can be divided into two realms: that of prose and that of verse. But where exactly does the boundary run between them? Thatโs simple, you may think. Prose is just words, whereas verse is words that have some sustained rhythm to them. True enough โ but itโs a little more complex than that. Not all verse is poetry, and not all poetry is verse.
Take a random proverb (โWhile the catโs away, the mice will playโ) or advertising slogan (โOnce you pop, you canโt stopโ). Both have a rhythm and feel that distinguishes them from prose, but poems they surely are not. Likewise, many a modern poem has little to mark it out as verse, other than its artistic (and often ideosyncratic) line-division on the page: set rhythms or rhyme schemes are no longer a poetic prerequisite. Music lyrics have their own rhythmical schemes, and are evidently a kind of verse โ but does this make โSheโll think Iโm superman, not super minivanโ or โpenalty shootouts are highly overrated!โ or โI turn an injury into tumidityโ poetry? Iโll let that be your call.

Where then do these words come from, this ‘proseโ, โverseโ and โpoetryโ? The answer is Latin: prose (from prosus, the shortened form of pro-versus) is โstraightforwardโ speech; verse (versus) is something โturnedโ into a particular form or shape; and poetry (poฤsis) is the work of an artist (poฤta). In fact, this last pair of words comes directly from the Ancient Greeks (ฯฮฟฮนฮตแฟฮฝ / poiein = โto make or doโ), whose culture drove so much of Romeโs own artistic endeavours. And, despite the myriad complexities of these two cultures, the line drawn between prose and verse was obvious and impermeable.
So letโs open the door a little into Greek and Roman โmetreโ โ the system that measured out their verse. To many newcomers this is a world of bewildering jargon, of terms that seem better suited to the laboratory โ โsynizesisโ, โReizianumโ, โtelesilleanโ โ or the zoo โ โlesser asclepiadsโ, โlimping iambicsโ and the occasional โcatalexisโ. But the basic principle of the system is astoundingly simple. Each syllable of a word is classed as โlongโ or โshortโ (or, more properly, โheavyโ and โlightโ), and each metre is a set pattern of these long and shorts.

To begin with English, letโs consider the shortest and longest words of one syllable: โaโ is scarcely a split-second blurt when it appears in a phrase such as โin a bitโ, but โstrengthsโ, the longest monosyllable in the language,[1] takes an appreciable time to sound out. We thus have a clear pair of short and long syllables, but itโs anybodyโs guess how to class middling words, such as โcrackโ or โblogโ: if they have to be either longs or shorts, who makes the call and how do they know?
Thankfully, this is not how we do things in English poetry. But the Greeks and the Romans, when faced with similar problems, decided to operate with a false binary, whereby any syllable of any word was marked either short or long. Simply put, their rules were as follows:
- Every syllable in Latin and Greek has a vowel at its heart. If that vowel is itself pronounced long, or two vowels are combined in one sound (a โdiphthongโ), that syllable is long (typically marked with the longum โ ). So, if we transferred this into English, bone, thigh, feet and heart would all be long.
- If the vowel in the syllable is instead short, that syllable is short (marked with a breve, แด ), except:
-
- If a short vowel is followed by two consonants (or double-consonants like x = ks), which means that the syllable is pronounced with a consonant at its end, that syllable is long.
So, if we were to apply this system to English, leg and rib would be treated as short, but hand and neck as long.
Turning to Latin, where weโll stay for the rest of this piece, a pair of Latin words such as fฤs est (โit is rightโ) would sound โ or โscanโ โ as two long syllables (โ โ), pater (โfatherโ) as two shorts (แด แด), and mฤius flet (โhe weeps louderโ) as long-long-short (โ โ แด). Our life is made easier in Latin when we mark all naturally long vowels with the macron above them (e.g. leล), so we know that they are to be sounded differently. But the worldโs a funny place, and most of us who work professionally with Latin donโt bother doing this.

With this as the basic system, letโs focus now on a single metre โ the dactylic hexameter. This name sounds terribly technical, but itโs simple enough: six (hexa-) measures (metra) of finger-shaped (dactyli = Greek ฮดฮฌฮบฯฯ ฮปฮฟฮน, daktuloi = โfingersโ) rhythms. Take a look at your finger to reveal the beat: itโs composed of three parts, a long part first, then two short bits (โ แด แด). Repeat this unit (a โfootโ of the line as a whole) six times, and you have the basic form of the hexameter.
But since an endless stream of this โtum-ti-tiโ triple-rhythm would be mind-numbingly dull, the end of each line is signalled by replacing the last foot with its metrical equivalent of two longs (โ โ : the solemn โspondeeโ). In fact, you can mix up any of your dactyls with this spondee whenever and wherever you fancy, or when the words you need to use demand it. You then keep going for as long as you, or your audience, can stomach.

The rhythm of the dactylic hexameter is as old as the hills. Itโs there from the very start of Greek literature, from the first to last line of Homerโs epic poems the Iliad and Odyssey (perhaps written in the 8th century BC). It also was the metre that marked a new start for Latin poetry. Quintus Ennius (239โ169 BC), a trilingual southern Italian who made his living as a Rome-sponsored poet, decided to reject the native Italian verse-forms (which operated on rules so different that scholars donโt fully understand them!) and to adopt instead the iconic rhythm of the Greeksโ dactylic hexameter.
The good news was that this placed his own poetry in the grand and unbroken tradition that already stretched back for almost a millennium. The bad news: Latin is much less suited to the metre, as the language has appreciably fewer short syllables than Greek. So you have to work harder to hammer out valid dactyls. Yet the die was cast, the mould set, and Ennius and his myriad successors had to make do.
Letโs look at the very first line of Latin hexameter poetry, the opening of Enniusโ mytho-historic epic, the Annales:
Mลซsae, quae pedibus magnum pulsฤtis Olympum
Muses, you who strike great Mt Olympus with your feet!
Its six feet break down easily enough: Mลซsae (โ โ), quae pedi– (โ แด แด), –bus mag– (โ โ), –num pul- (โ โ), –sฤtis Ol– (โ แด แด), –ym-pum (โ โ). That weighty opening word Musae sets the tone well. But itโs worth noting that Ennius couldnโt have begun the line with the proper Latin word for goddesses, deae (แด โ), or even for Italyโs native Muses, Camฤnae (แด โ โ), because neither opens with the long syllable that must start every hexameter line. In the rule-bound world of Greek and Latin metre, either the verse scans properly, or else it does not, and therefore cannot be written at all: a nearly metrical line is an entirely impossible line. So stay sharp.

The hexameter poses some other problems. Imagine, as a good-olโ-fashioned Roman, you want to include in your poetry some concepts that you hold dear โ vฤritฤs (โtruthโ) and Latฤซnitฤs (โgood Latinโ), say, or being dฤซligens (โdiligentโ) or perspicax (โinsightfulโ). Major problem, Iโm afraid: none of these words can ever be used. Why? Because they contain the rhythm long-short-long (โ แด โ), which canโt fit anywhere in the line.
Even if you put these words in a different grammatical case (e.g. vฤrฤญtฤtem or perspฤญcฤcฤซ), you can see youโre still stuck. So we can have the strange scenario that the most famous poem in Latin, Virgilโs Aeneid (20s BC), which is all about the founding of a new and world-changing state, cannot use the proper Latin word for that, cฤซvฤญtฤs. And you can forget about including philosophia and its outlandish sequence of five shorts!
What about if your poem has been paid for by someone whose name just doesnโt fit into it? How to name-drop and flaunt your gratitude? Virgil (70โ19 BC) had this problem with his Eclogues (c. 38 BC), in which he really ought to mention his patron Pollio (โ แด โ). The only way to squeeze his name in is to cut off the final long “o” by ensuring that it is obscured, or “elided”, by a following word that begins with a vowel. If the mouth doesnโt close when saying these two words, the unwieldy –ล can hopefully be slurred out of the picture. So Virgil does exactly this: Polliล amat (โPollio loves,โ 3.84, 88), akwardly forging the dactyl Polliโ am– (โ แด แด).[2]

Ovid (43 BC โ c. AD 17/18), writing a generation later, is rather cheekier. In one of his poetic โLetters from the Black Seaโ (Epistulae ex Ponto 4.12), he rebukes his friend Tuticanus (Tลซticฤnus), who has impudently complained that no poem has been dedicated to him. The reasons, Ovid says, are clear enough: with such an awkwardly shaped friend, my hands are tied. Iโm hardly going to chop your name up (nomen scindere) into two verses (in geminos versus), ending one line with Tลซtiยญ– and beginning the next with -cฤnus! Nor am I going to butcher it by mispronunciation, so that with an artificially short โaโ it can somehow fit: Tลซticฤnum. Your name, dear boy, just canโt cut the dactylic mustard. But donโt worry, Tutes, itโd work a treat in other metres โ in iambics, in hendecasyllables, or even in galloping galliambics.[3] Perhaps more on those another time.
You may fairly wonder whether this system survive at all in modern poetry. In English, itโs a quite different story: the general plan is instead to use patterns of natural word stress (โaccentโ), of rhyme, and often of both. Most of Shakespeareโs lines, for instance, are sequences of ten syllables, with the word stress on every even-numbered syllable. As Twelfth Night (1601?) famously opens,
If music be the food of love, play on!
Still, a few hardy souls have tried to match ancient Greek and Roman metres with the English word accent. Take an exchange from Henry Wadsworth Longfellowโs Courtship of Miles Standish (1858), and try to ride the hexametric wave of dactyls and spondees:
You are a writer, and I am a fighter, but here is a fellow
Who could both write and fight, and in both was equally skilful!
Romping stuff. Well, here’s more:
Yes, he was equally skilled, as you say, with his pen and his weaponsโฆ
Truly a wonderful man was Caius Julius Caesar!
Lord Tennyson, never one to mince his words, had other ideas about such endeavours:
These lame hexameters the strong-wingโd music of Homer!
When was a harsher sound ever heard, ye Muses, in England?[4]
Well, Longfellow or Wrongfellow, it was a very different story for the Greeks and Romans. Far from sounding repetitive or like trivial jingle-jangle, this was the mightiest metre of antiquity, big enough to convey epic tales, grand enough to channel divine hymns and powerful enough to pack the punch of satire.
Almost all the most famous poets of antiquity, not just Homer and Virgil, but the mighty names of Hesiod, Callimachus, Lucretius, Horace, Lucan, Juvenal and many scores more used the hexameter over countless thousands of lines. And Ovid, author of the poem that has influenced western art more than any other, the Metamorphoses (AD 8), chose this very verse form for his playful fifteen-book tour through each and every myth he could conjure up. Three thousand years on, and the hexameter remains a classic โ a vintage staple that may not have rhyme but still has good reason to resonate.

Further Reading
There is no good introductory handbook to Greek and Latin metre. At the more technical level, there is plenty of useful information in the twin volumes of D.S. Raven (Greek Metre, London, 1962; Latin Metre, London, 1965; both reprinted by the much-missed Bristol Classical Press in 1998), but Martin West’s Greek Metre (Oxford UP, 1982; issued as a still substantial Introduction in 1987) remains magisterial.
A series of ten lectures on Greek and Latin metre, with accompanying handouts, can be found on Antigone here.
