The Sun Rising (also known as "The Sunne Rising") is a thirty line poem with three stanzas published in 1633 by poet John Donne.
 The meter is irregular, ranging from two to six stresses per line in no fixed pattern.
 The longest lines are at the end of the three stanzas and the rhyme never varies—each stanza runs 'abbacdcdee'.
 Donne's poems were known to be metaphysical with jagged rhythms, dramatic monologues, playful intelligence, and startling images.
 The poem personifies the sun and stanza one begins with the speaker in bed with his lover, complaining about its beaming rays.
 Donne uses expressions such as, "Busy old fool" (line 1) and "Saucy Pedantic Wretch" [perfectionist] (line 5) to describe his annoyance with it.
 The speaker of the poem questions the sun's motives and yearns for the sun to go away so that he and his lover can stay in bed.
A sestain is a six line poem or repetitive unit of a poem of this format (musaddas), comparable to quatrain (Ruba'i in Persian and Arabic) which is a four line poem or a unit of a poem.
 There are many types of sestain with different rhyme-schemes, for example aabbcc, ababcc, aabccb or aaabab.
 The sestains are probably next in popularity to quatrains in European literature.
 Usually there are three rhymes in the six-line strophe, but sometimes there are only two.
The Wulfings, Wylfings or Ylfings (the name means the "wolf clan") was a powerful clan in "Beowulf", "Widsith" and in the Norse sagas.
 While the poet of "Beowulf" does not locate the Wulfings geographically, Scandinavian sources define the Ylfings (the Old Norse form of the name) as the ruling clan of the Eastern Geats.
Carrickfergus is a 44-line poem by Louis MacNeice.
 It was written in 1937 and first published in book form in MacNeice's poetry collection "The Earth Compels" (1938).
 The poem reflects on MacNeice's childhood in Carrickfergus, a large town in County Antrim, Northern Ireland.
 Although the title of the poem is "Carrickfergus", the text of the poem refers to "Carrick", as the town is known locally and colloquially.
June Thunder is a 28-line poem by Louis MacNeice.
 It was first published in book form in MacNeice's poetry collection The Earth Compels (1938).
 The poem begins with memories of idyllic summer days in the countryside - "the unenduring / Joys of a season" - before returning to the present and "impending thunder".
 "June Thunder" is written in a loose form of the sapphic stanza, with three lines set in falling rhythm followed by a shorter fourth line.
 The poem was anthologised in "A New Anthology of Modern Verse 1920-1940" (1941), edited by Cecil Day-Lewis and L.A.G. Strong, and "Penguin New Writing" No. 2 (January 1941).
"Epilogue For W. H. Auden" is a 76-line poem by Louis MacNeice.
 It was written in late 1936 and was first published in book form in "Letters from Iceland", a travel book in prose and verse by W. H. Auden and Louis MacNeice (1937).
 MacNeice subsequently included it as the last poem in his poetry collection "The Earth Compels" (1938).
 "Epilogue For W. H. Auden" reviews the Iceland trip MacNeice and Auden had taken together in the summer of 1936; the poem mentions events that had occurred while MacNeice and Auden were in Iceland, such as the fall of Seville (marking the start of the Spanish Civil War) and the Olympic Games in Berlin.
Siege of Thebes is a 4716 line poem written by John Lydgate between 1420 and 1422.
 Lydgate composed the Siege of Thebes directly following his composition of Troy Book - which was patronized by King Henry V - and directly preceding his production of Fall of Princes - which Humphrey Duke of Gloucester patronized during King Henry VI's regency.
 The poem is particularly significant because it was written without an identifiable patron, and most probably without patron or commission whatsoever.
 But, whatever the status of its patronage, the Siege of Thebes still managed to gain significant popularity, attested to by its 31 surviving manuscripts.
 The poem is, in large part, a response to Geoffrey Chaucer's The Canterbury Tales.
 Lydgate's poem borrows The Canterbury Tales pilgrimage-based framing device and is written as an additional tale in the cycle.
 However, unlike Chaucer, Lydgate establishes himself as the narrator of the work, and recounts the Siege of Thebes.
 Lydgate's Siege of Thebes follows and expands upon the Theban Cycle, but makes significant additions to the source materials.
Rugby Football Excursion is a 44-line poem by Louis MacNeice.
 It was written in 1938 and first published in book form in MacNeice's poetry collection The Earth Compels (1938).
 The poem recounts an excursion taken by MacNeice from London to Dublin, in order to watch a rugby football match at Lansdowne Road stadium.
 MacNeice does not specify the occasion, but internal evidence from the poem establishes the match as a rugby football international between Ireland and England on 12 February 1938; England won the match by 36 points to 14.
"Equitan" is a Breton lai, a type of narrative poem, written by Marie de France sometime in the 12th century.
 The poem belongs to what is collectively known as "The Lais of Marie de France".
 Like the other lais in the collection, "Equitan" is written in the Anglo-Norman language, a dialect of Old French, in rhyming octosyllabic couplets.
 In this 320 line poem, the author cautions that those who plot to harm another person may find only their own misfortune.
Widsith is an Old English poem of 143 lines.
 The poem survives only in the Exeter Book, a manuscript of Old English poetry compiled in the late 10th century containing approximately one sixth of all surviving Old English poetry.
 Widsith is located between the poems "Vainglory" and "The Fortunes of Men".
 Since the donation of the Exeter Book in 1076, it has been housed in Exeter Cathedral in southwest England.
 The poem is for the most part a survey of the people, kings, and heroes of Europe in the Heroic Age of Northern Europe: see Tribes of Widsith.
