Terzanelle: A terzanelle is a poetic form combining aspects of the villanelle and the terza rima.  It is nineteen lines total, with five triplets and a concluding quatrain.  The middle line of each triplet stanza is repeated as the third line of the following stanza, and the first and third lines of the initial stanza are the second and final lines of the concluding quatrain; thus, seven of the lines are repeated in the poem.  The rhyme scheme and stanzaic structure are as follows (a capitalized letter indicates a line repeated verbatim):

Guests of the Nation: "Guests of the Nation" is a short story written by Frank O'Connor, first published in 1931, portraying the execution of two Englishmen held captive by the Irish Republican Army during the War for Independence.  The story is split into four sections, each section taking a different tone.  The first reveals a real sense of camaraderie between the English prisoners.  With the two Englishmen being killed, the final lines of the story describe the nauseating effect this has on the Irishmen.

Horatio (Hamlet): Horatio is a character in William Shakespeare's tragedy "Hamlet".  Horatio's origins are unknown, although he was present on the battlefield when Hamlet's father defeated 'the ambitious Norway', Fortinbras (the king), and attended Wittenberg University with Prince Hamlet.  Horatio is evidently not directly involved in the intrigue at the Danish court; thus, he makes a good foil or sounding board for Prince Hamlet.  He is often not identified as any specific court position, but simply as "friend to Hamlet."

Starbase Indy: Starbase Indy is a science fiction convention.  Its mission, revised in 2017, is "Celebrating Star Trek's vision of the future by promoting humanitarianism and STEM education today."

Literary influence of Hamlet: William Shakespeare's Hamlet is a tragedy, believed to have been written between 1599 and 1601.  It tells the story of Hamlet, Prince of Denmark—who takes revenge on the current king (Hamlet's uncle) for killing the previous king (Hamlet's father) and for marrying his father's widow (Hamlet's mother)—and it charts the course of his real or feigned madness.  "Hamlet" is the longest play—and Hamlet is the largest part—in the entire Shakespeare canon.  Critics say that "Hamlet" "offers the greatest exhibition of Shakespeare's powers".

Triolet: A triolet ( or ) is almost always a stanza poem of eight lines, though stanzas with as few as seven lines and as many as nine or more have appeared in its history.  Its rhyme scheme is "ABaAabAB" and in 19th century English triolets often all lines are in iambic tetrameter, though in traditional French triolets from the 17th century on the second, sixth and eighth lines tend to be iambic trimeters followed by one amphibrachic foot each.  In French terminology, a line ending in an iambic foot was denoted as masculine, while a line ending in an amphibrachic foot was called feminine.  Depending on the language and era, other meters are seen, even in French.  The first, fourth and seventh lines are identical, as are the second and final lines, thereby making the initial and final couplets identical as well.  In a traditional French triolet, the second and third non-repeating lines rhyme with the repeating first, fourth, and seventh lines, while the non-repeating sixth line rhymes with the second and eighth repeating lines.  However, especially in German triolets of the 18th and 19th centuries, one will see this pattern often violated.

Fortinbras: Fortinbras is either of two minor fictional characters from William Shakespeare's tragedy "Hamlet".  The more notable is a Norwegian crown prince with a few brief scenes in the play, who delivers the final lines that represent a hopeful future for the monarchy of Denmark and its subjects.  Fortinbras is also the name of the former king of Norway and father of the crown prince Fortinbras.  King Fortinbras was slain in the play's antecedent action in battle with King Hamlet.  The battle between the two is described by Horatio in Act One, Scene One (I,i) of the play.

Doina (Eminescu): Doina, or Doină (sometimes translated as "Lament"), is a political poem by the Romanian Mihai Eminescu.  It was first published in 1883 and is therefore seen by some as Eminescu's final work in verse, although it may actually be an 1870s piece, inspired or enhanced by the perceived injustice of the Berlin Treaty.  A variation of the "doina" (plural: "doine"), picked up from Romanian folklore, it is noticeably angry to the point of rhetorical violence, a radical expression of Romanian nationalism against invading "foreigners", noted for its hints of ecopoetry and "anti-technicist" discourse.  "Doina" delineates the ideal geographical space of Greater Romania, at a time when Romanian-inhabited regions were divided between an independent kingdom and multinational empires.  Its final lines call on Stephen the Great, depicted as a sleeping hero, to take up the cause of Romanians and chase foreigners out with the sound of his horn.  The same basic themes appear in another poem by Eminescu, the anthem-like "La arme" ("To Arms"), which is sometimes discussed as a variant of "Doina".

Meno: Meno ( ; Greek: Μένων ) is a Socratic dialogue written by Plato.  It appears to attempt to determine the definition of virtue, or "arete", meaning virtue in general, rather than particular virtues, such as justice or temperance.  The first part of the work is written in the Socratic dialectical style and Meno is reduced to confusion or aporia.  In response to Meno's paradox (or the learner's paradox), however, Socrates introduces positive ideas: the immortality of the soul, the theory of knowledge as recollection ("anamnesis"), which Socrates demonstrates by posing a mathematical puzzle to one of Meno's slaves, the method of hypothesis, and, in the final lines, the distinction between knowledge and true belief.

Rorarii: Rorarii were soldiers who formed the final lines, or else provided a reserve thereby, in the ancient pre-Marian Roman army.  They may have been used with the "triarii" in battle near the final stages of fighting, since they are recorded as being located at the rear of the main battle formation.  (Note that the saying "Going to the Triarii" means that something has gone to the bitter end – as in reached the final line.)
