Siluan (; 14th century) was a Serbian Orthodox monk and poet who lived and worked in the Hilandar monastery at Mount Athos in the 14th century.
 Very little is known about him.
 The mystical tradition of prayer known as hesychasm left a strong imprint in Serbian medieval literature and art, which is evident already in the works of Domentijan and Teodosije the Hilandarian, but most prominently in the writings of archbishop Danilo II, patriarch Jefrem, monk Isaija and Siluan.
 Siluan is the author of hymns to Saint Sava and St. Simeon (Stefan Nemanja).
 History knows of two Serbian monks called Siluan active on Athos, living two centuries apart, but researchers have been inclined to credit the 14th century Siluan with the authorship of "Verses for St. Simeon" and "Verses for Sava".
 The analyses of the two Old Serbian verbal ornaments, attributed to the 14th-century Siluan, appear in the work of Roman Jakobson; Siluan is presented as one of the most enlightened poets of his time, with an amazing ability to condense meditative philosophy into few words.
De viris illustribus (English: On Illustrious Men ) is an unfinished collection of biographies, written in Latin, by the 14th century Italian author Francesco Petrarca.
 These biographies are a set of Lives similar in idea to Plutarch's "Parallel Lives".
 The works were unfinished however he was famous enough for these and other works to receive two invitations to be crowned poet laureate.
 He received these invitations on exactly the same day, April 8, 1341, one being from the Paris University and the other from the Roman Senate.
 He accepted the Roman invitation.
Intabulation, from the Italian word "intavolatura", refers to an arrangement of a vocal or ensemble piece for keyboard, lute, or other plucked string instrument, written in tablature.
 It was a common practice in 14th–16th century keyboard and lute music.
 A direct effect of intabulation was one of the early advantages of keyboards, the ability to render multiple instruments' music on one instrument.
 The earliest intabulation is from the mid-14th century Robertsbridge Codex, also one of the first sources of keyboard music still in existence.
 Some other early sources of intabulated music are the Faenza and Reina manuscripts (from the 14th century) and the Buxheim manuscript (from the 15th century).
 The Faenza manuscript,the largest of these early manuscripts, written circa 1400, contains pieces written or transcribed in the 14th century, such as those by Francesco Landini and Guillaume de Machaut.
 More than half of its pieces are intabulations.
 The large Buxheim manuscript is dominated by intabulations, mainly of prominent composers of the time, including John Dunstaple, Gilles Binchois, Walter Frye, and Guillaume Dufay.
 The term "intabulation" continued to be popular through the 16th century, but fell out of use in the early 17th century, though the practice continued.
 The exception is the 16th- and 17th-century Italian keyboard pieces which included both vocal and instrumental music.
 Intabulations contain all the vocal lines of a polyphonic piece, for the most part, although they are sometimes combined or redistributed in order to work better on the instrument the intabulation is intended for, and idiomatic ornaments are sometimes added.
The Liber sine nomine (The Book without a Name) is a collection of nineteen personal letters written in Latin by the fourteenth century Italian poet and Renaissance humanist Petrarch.
 The letters being harshly critical of the Avignon papacy, they were withheld from the larger collection of his "Epistolae familiares" ("Letters to Friends") and assembled in a separate book.
 In this fashion, Petrarch reasoned, a reader could throw away this collection, and the other letters to friends could be preserved for posterity.
