Sultan Saladin is the correct answer. He was placed in limbo because he was an honorable man, despite being a non-Christian. Sultan Saladin was a contemporary of Richard the Lionheart and conquered Jerusalem in the Second and Third Crusades. Others in limbo in The Divine Comedy include Julius Caesar, Hector, and Avicenna.

The sonnet was first developed in thirteenth- and fourteenth-century Italy, but became a popular form of poetry throughout Europe during the Renaissance. William Shakespeare became well known in England for his sonnets in the late sixteenth century. A sonnet typically has just fourteen strictly metered lines, with a specific structure and strict rhyme scheme.

Iambic pentameter is most famous as the rhythm scheme used by William Shakespeare in most of his plays. The scheme features five "feet" per line, with each foot having one unstressed syllable followed by one stressed syllable. This rhythm creates a standard speaking pattern for actors and audiences to follow.

Petrarch, who lived from 1304 to 1374, is not just famous for writing most of his poems in the sonnet form, but for widely popularizing the form across Europe. Petrarch used a standard fourteen line form with an ABBA rhyme scheme. Petrarch is considered one of the standardizers of the Italian language thanks to his immense popularity.

When a rhyme scheme is described with letters, the first line automatically gets designated as "A." Any other line that rhymes with the first line will also be marked as "A." Therefore, in an ABBA rhyme scheme, the first and the fourth lines rhyme, as do the second and third lines.

"Sonnet" is the correct answer, as sonnets utilize iambic pentameter and a concluding couplet and are usually made up of fourteen lines. The most famous writer of English sonnets is William Shakespeare, who wrote one hundred and fifty-four sonnets during his lifetime.

The poetry of William Shakespeare fit most of the conventions of sixteenth century English poetry, and as such he used the meter of iambic pentameter almost exclusively. Iambs refer to the "feet," or stress breaks, in poetry that are a short syllable followed by a long syllable, while "pentamater" refers to there being five, from the Greek "penta," feet. Thus, an iambic pentameter line is meant to be said with a rhythm of "da-DUH, da-DUH, da-DUH, da-DUH, da-DUH."

The poem is Sonnet 29 by William Shakespeare. The rhyme scheme is four quatrains and an ending couplet. The couplet, or last two lines, rhyme with each other, but not with other lines earlier in the poem.

The Canterbury Tales was a landmark work in English literature as one of the earliest works written in vernacular English, which in the late fourteenth century was Middle English. The Canterbury Tales' author, Geoffrey Chaucer, was most likely inspired by the works of Bocaccio and Dante, which he would have encountered in diplomatic trips to Italy. The Canterbury Tales consist of over twenty unrelated tales, loosely bound together by the fact that they are all told by pilgrims on a trip to Canterbury cathedral.

Rumi was a distinctly accomplished Persian poet viewed strictly from a literary standpoint. His thoughts on Islam were also formative in developing the mystical form of the religion known as Sufism. His works are still read in their original language, but have also gained recognition from around the world.
