Libellus de Medicinalibus Indorum Herbis

The Libellus de exordio atque procursu istius, hoc est Dunhelmensis, ecclesie (English: Tract on the Origins and Progress of this the Church of Durham ), in short Libellus de exordio, is a historical work of marked literary character composed and compiled in the early 12th-century and traditionally attributed to Symeon of Durham.
 It relates the history of bishopric and church of Durham and its predecessors at Lindisfarne and Chester-le-Street ("Cunecacestre").
 It is sometimes also known as the Historia Dunelmensis ecclesiae (English: "History of the Church of Durham").
The Germanic substrate hypothesis is an attempt to explain the distinctive nature of the Germanic languages within the context of the Indo-European languages.
 It claims that the elements of the Common Germanic vocabulary and syntactical forms, which do not seem to have cognates in other Indo-European languages, suggest that Proto-Germanic may have been either a creole or a contact language that subsumed a non-Indo-European substrate language or a hybrid of two quite different Indo-European languages, from the centum and satem types, respectively.
Icelandic (Icelandic: "íslenska" , ] ) is a North Germanic language, the language of Iceland.
 It is an Indo-European language belonging to the North Germanic or Nordic branch of the Germanic languages. Historically, it was the westernmost of the Indo-European languages prior to the colonisation of the Americas.
 Icelandic, Faroese, Norn, and Western Norwegian formerly constituted "West Nordic"; Danish, Eastern Norwegian and Swedish constituted "East Nordic".
 Modern Norwegian Bokmål is influenced by both groups, leading the Nordic languages to be divided into mainland Scandinavian languages and "Insular Nordic" (including Icelandic).
Libellus De Arte Coquinaria ("The Little Book of Culinary Arts") is a culinary manuscript containing thirty-five early Northern European recipes.
 The Collection is composed of four versions (or pieces) and consists of recipes in Danish, Icelandic, and Low German.
 Dating from the early thirteenth century, the libellus is considered to be among the oldest of culinary recipe collections.
 The cookbook exists in a three-part collection consisting of a book of herbs, one of stones, and "Libellus De Arte Coquinaria".
 The two former are written by Henrik Harpestræng.
Juan Badiano (1484-after 1552) was the translator of Libellus de Medicinalibus Indorum Herbis ca. 1552, from Nahuatl to Latin.
 The book was a compendium of 250 medicinal herbs used by the Aztecs.
 This compilation was originally done by Martin de la Cruz (another Indian who was baptised with this Christian name).
 This catalogue is a historic document, since it shows the Aztec's advancements in medicine.
 Badiano was born in Xochimilco, Mexico, and taught Latin in the school of Tlatelolco, where he attended with Martin de la Cruz and proved to be an outstanding student.
Latin (Latin: "lingua latīna" , ] ) is a classical language belonging to the Italic branch of the Indo-European languages.
 The Latin alphabet is derived from the Etruscan and Greek alphabets, and ultimately from the Phoenician alphabet.
Pre-Indo-European languages are any of several old languages, not necessarily related to one another, that existed in prehistoric Europe and South Asia before the arrival of speakers of Indo-European languages.
 The oldest Indo-European language texts date from 19th century BCE in Kültepe in modern-day Turkey, and while estimates vary widely, spoken Indo-European languages are believed to have developed at the latest by the third millennium BCE (see Proto-Indo-European Urheimat hypotheses).
 Thus the Pre-Indo-European languages must have developed earlier than, or in some cases alongside, the Indo-European languages.
This is a list of extinct languages of Europe, languages which have undergone language death, have no native speakers and no spoken descendant.
 As the vast majority of Europeans speak Indo-European languages, a result of the westward portion of the prehistoric Indo-European migrations, the bulk of the indigenous languages of Europe became extinct thousands of years ago without leaving any record of their existence as they were replaced with Celtic, Italic, Germanic, Balto-Slavic, Hellenic, and Iranian Indo-European languages.
 A small minority of these extinct languages, however, survived long enough to be attested.
The Indo-Aryan or Indic languages are the dominant language family of the Indian subcontinent.
 They constitute a branch of the Indo-Iranian languages, itself a branch of the Indo-European language family.
 Indo-Aryan speakers form about one-half of all Indo-European speakers (about 1.5 of 3 billion), and more than half of all Indo-European languages recognized by "Ethnologue".
 While the languages are primarily spoken in South Asia, pockets of Indo-Aryan languages are found to be spoken in Europe and the Middle East.
The Libellus de Medicinalibus Indorum Herbis (Latin for "Little Book of the Medicinal Herbs of the Indians") is an Aztec herbal manuscript, describing the medicinal properties of various plants used by the Aztecs.
 It was translated into Latin by Juan Badiano, from a Nahuatl original composed in the Colegio de Santa Cruz de Tlatelolco in 1552 by Martín de la Cruz that is no longer extant.
 The "Libellus" is also known as the Badianus Manuscript, after the translator; the Codex de la Cruz-Badiano, after both the original author and translator; and the Codex Barberini, after Cardinal Francesco Barberini, who had possession of the manuscript in the early 17th century.
