Dictionarium quatuor linguarum (The Dictionary of Four Languages) is a 16th-century book by the German polymath Hieronymus Megiser that includes a multilingual dictionary and a multilingual grammar of Italian, Slovene, German, and Latin.
 It also includes some Croatian words.
 It was compiled and published in 1592 in Graz (Austria), then part of the Habsburg Monarchy.
 The dictionary is the first multilingual dictionary of Slovene.
 The appendix, named "Exempla aliquot declinationum et coniugationium" (Some examples of declensions and conjugations) contains some grammar of the included languages and has been recognised as the second grammar of Slovene and the first multilingual grammar that includes Slovene.
 The book marks the beginning of Slovene lexicography.
 An extended edition was published under the same title in 1744 at Klagenfurt (Austria) by the Jesuits.
 This second edition also contains example phrases in German and Slovene, illustrating the use of the entries given.
 The number of Slovene equivalents in this edition is notably higher; they often reflect Carinthian Slovene.
Ibn Rushd (Arabic: ‎ ‎ ; 14 April 1126 – 10 December 1198), full name (Arabic: أبو الوليد محمد ابن احمد ابن رشد‎ , "ʾAbū l-Walīd Muḥammad Ibn ʾAḥmad Ibn Rushd " ‎ ), often Latinized as Averroes ( ), was a medieval Andalusian polymath.
 He wrote on logic, Aristotelian and Islamic philosophy, theology, the Maliki school of Islamic jurisprudence, psychology, political and Andalusian classical music theory, geography, mathematics, and the mediæval sciences of medicine, astronomy, physics, and celestial mechanics.
 Ibn Rushd was born in Córdoba, Al Andalus (present-day Spain), and died at Marrakesh in present-day Morocco.
 His body was interred in his family tomb at Córdoba.
 The 13th-century philosophical movement in Latin Christian and Jewish tradition based on Ibn Rushd's work is called Averroism.
The Nowell Codex is the second of two manuscripts found in the bound volume Cotton Vitellius A.xv, one of the four major Anglo-Saxon poetic manuscripts.
 It is most famous as the manuscript containing the unique copy of the epic poem "Beowulf".
 In addition to this, it contains first a fragment of "The Life of Saint Christopher", then the more complete texts "Wonders of the East" and "Letters of Alexander to Aristotle," and, after "Beowulf", a poetic translation of "Judith".
 Due to the fame of "Beowulf", the Nowell codex is also sometimes known simply as the Beowulf manuscript.
 The manuscript is located within the British Library with the rest of the Cotton collection.
Avempace (c. 1085  – 1138) is the Latinate form of Ibn Bâjja (Arabic: ‎ ‎ ), full name Abû Bakr Muḥammad Ibn Yaḥyà ibn aṣ-Ṣâ’igh at-Tûjîbî Ibn Bâjja al-Tujibi ( ), a medieval Andalusian: his writings include works regarding astronomy, physics, and music, as well as philosophy, medicine, botany, and poetry.
Abū al‐Ṣalt Umayya ibn ʿAbd al‐ʿAzīz ibn Abī al‐Ṣalt al‐Dānī al‐Andalusī (c. 1068 October 23, 1134), known in Latin as Albuzale, was an Andalusian polymath whose works on astronomical instruments were read both in the Islamic world and Europe.
 He also worked as a physician, a teacher of alchemy, and wrote treatises on medicine, philosophy, music, and history.
 He became well known in Europe through translations of his works made in the Iberian Peninsula and in southern France.
 He is also credited with introducing Andalusian music to Tunis, which later led to the development of the Tunisian ma'luf.
Abu al-Qasim Abbas ibn Firnas ibn Wirdas al-Takurini (810–887 A.D.), also known as Abbas ibn Firnas (Arabic: عباس بن فرناس‎ ‎ ), was an Andalusian polymath: an inventor, physician, chemist, engineer, Andalusian musician, and Arabic-language poet.
 Of Berber descent, his name's root is AFERNAS, which is fairly widespread today in Morocco and Algeria.
 He was born in Izn-Rand Onda, Al-Andalus (today's Ronda, Spain), lived in the Emirate of Córdoba, and is reputed to have attempted flight.
Boutilimit (Arabic: بوتلميت‎ ‎ ) lies 164 km south east of Mauritania's capital of Nouakchott.
 The town has been an important center of religious scholarship and training since its founding by an Islamic mystic and scholar in the 19th Century.
 Although desertification has sapped much of the community's economic energy, it remains the most important center of religious training in Mauritania.
 Its Qur'anic school is known for its library of manuscripts, set up by Shaykh Sidiyya "al-Kabir" (1774–1868), which is second only to the collection found in the ancient Mauritanian city of Chinguetti.
 A unique copy of a grammar by Averroes was recently found there.
Unique Copy Album is the name of a unique copy release of an album by the Swiss band The bianca Story.
The Cancionero de Upsala ["sic"] , also known by the titles Cancionero del Duque de Calabria and Cancionero de Venecia, is a volume of mostly anonymous Spanish music printed in Venice in 1556.
 Its actual title is "Villancicos de diuersos Autores, a dos, y a tres, y a quatro, y ya a cinco bozes...Venetiis, Apud Hieronymum Scotum, MDLVI".
 It survives in a unique copy at the Uppsala University Library and was edited in 1909 by Rafael Mitjana; the subsequent literature has mostly adopted his spelling "Upsala" (""Upsala"" being the historic Swedish spelling of "Uppsala" until the major spelling reform of 1906).
 A facsimile was first published by Alamire (Peer, Belgium 1984) and later by the Biblioteca Valenciana (Valencia, Spain 2003).
Nazhun al-Garnatiya bint al-Qulai’iya (eleventh-century) was a Granadan courtesan and poet, noted for her outrageous verse, her learning, and her low-status origins (possibly as a slave).
 Although little of her work survives, she is, among medieval Andalusian women poets, second only to her contemporary Hafsa Bint al-Hajj al-Rukuniyya in the quantity of her work preserved; she usually appears getting the better of male poets and aristocrats around her with her witty invective.
 In Marla Segol's words, "as a rule, Nazhun represents her body in ways that disrupt conventional strategies for control of women’s speech and sexuality, and protests the merchandising of women’s bodies."
