Ruba'i

Ruba'i is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Ruba'i rather than just read about it. In short: A rubāʿī (Classical Persian: رباعی, romanized: robāʿī, from Arabic رباعيّ, rubāʿiyy, 'consisting of four, quadripartite, fourfold'; plural: رباعيّات, rubāʿiyyāt) or chahārgāna(e) (Classical Persian: چهارگانه) is a poem or a verse of a poem in Persian poetry (or its derivative in English and other languages) in the form of a quatrain, consisting of four lines (four hemistichs). In classical Persian poetry, the ruba'i…

Key takeaways

  • Ruba'i belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Ruba'i to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Ruba'i from memory before moving on to harder problems.

Reference excerpt

A rubāʿī (Classical Persian: رباعی, romanized: robāʿī, from Arabic رباعيّ, rubāʿiyy, 'consisting of four, quadripartite, fourfold'; plural: رباعيّات, rubāʿiyyāt) or chahārgāna(e) (Classical Persian: چهارگانه) is a poem or a verse of a poem in Persian poetry (or its derivative in English and other languages) in the form of a quatrain, consisting of four lines (four hemistichs). In classical Persian poetry, the ruba'i is written as a four-line (or two-couplet / two-distich) poem, with a rhyme-scheme A A B A {\displaystyle \mathrm {AABA} } or A A A A {\displaystyle \mathrm {AAAA} } . This is an example of a ruba'i from Rumi's Divan-e Shams:

Anwār-i Ṣalāḥ-i Dīn bar angēkhta bād Dar dīda (w)u jān-i ʿāshiqān rēkhta bād Har jān ki laṭīf gasht u az luṭf guzasht Bā khāk-i Ṣalāḥ-i Dīn dar-āmēkhta bād May the splendors of Salahuddin be roused, And poured into the eyes and souls of the lovers. May every soul that has become refined and has surpassed refinement Be mingled with the dust of Salahuddin!

Metre

The usual metre of a Persian ruba'i, which is used for all four lines of the above quatrain by Rumi, is, as follows:

– – u u – u – u – – u u – In the above scheme, quantitatively, "–" represents a long syllable, and "u" a short one. As variations of this scheme, any sequence of – u, except the final syllable of each line, can be replaced by a single "overlong" syllable, such as gēkh, tīf, luṭf in the poem above, containing either a long vowel followed by a consonant other than "n", or a short vowel followed by two consonants. An overlong syllable, as mentioned, can freely be substituted for the final syllable of the line, as with bād above. Another variation, as a poetic licence rule, is that occasionally a sequence of two short syllables (u u) can be replaced by a single long one (–). A third variation is to use the same metre as above, but with the sixth and seventh syllables reversed:

– – u u – – u u – – u u –

In English The verse form AABA as used in English verse is known as the Rubaiyat Quatrain due to its use by Edward FitzGerald in his famous 1859 translation, Rubaiyat of Omar Khayyam. Algernon Charles Swinburne, one of the first admirers of FitzGerald's translation of Khayyam's medieval Persian verses, was the first to imitate the stanza form, which subsequently became popular and was used widely, as in the case of Robert Frost's 1922 poem "Stopping by Woods on a Snowy Evening".

FitzGerald's translation became so popular by the turn of the century that hundreds of American humorists wrote parodies using both the form and, to varying degrees, the content of his stanzas. These included The Rubaiyat of Ohow Dryyam, The Rubáiyát of a Persian Kitten, The Rubaiyat of Omar Cayenne, and The Rubaiyat of Omar Khayyam Jr. In extended sequences of ruba'i stanzas, the convention is sometimes extended so that the unrhymed line of the current stanza becomes the rhyme for the following stanza. The structure can be made cyclical by linking the unrhymed line of the final stanza back to the first stanza: ZZAZ. These more stringent systems were not, however, used by FitzGerald in his Rubaiyat.

Worked examples

Example 1 — a first encounter with Ruba'i

Start with the simplest possible case. Write down what Ruba'i claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ruba'i before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ruba'i ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ruba'i

In research
Ruba'i appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Ruba'i in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Ruba'i is common in secondary-school and first-year university syllabi. It links to neighbouring topics Iranian inventions, Literary genres, Medieval poetry, so understanding it makes those chapters shorter.
In everyday life
Look for Ruba'i outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

A rubāʿī (Classical Persian: رباعی, romanized: robāʿī, from Arabic رباعيّ, rubāʿiyy, 'consisting of four, quadripartite, fourfold'; plural: رباعيّات, rubāʿiyyāt) or chahārgāna(e) (Classical Persian: چهارگانه) is a poem or a verse of a poem in Persian poetry (or its derivative in English and other l…

Why does Ruba'i matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Ruba'i?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
