EtymologiaeW
Etymologiae

Etymologiae, also known as the Origines ("Origins") and usually abbreviated Orig., is an etymological encyclopedia compiled by Isidore of Seville (c. 560–636) towards the end of his life. Isidore was encouraged to write the book by his friend Braulio, Bishop of Saragossa. The Etymologies summarized and organized a wealth of knowledge from hundreds of classical sources; three of its books are derived largely from Pliny the Elder's Natural History. Isidore acknowledges Pliny, but not his other principal sources, namely Cassiodorus, Servius and Solinus. The work contains whatever Isidore, an influential Christian bishop, thought worth keeping. Its subject matter is extremely diverse, ranging from grammar and rhetoric to the earth and the cosmos, buildings, metals, war, ships, humans, animals, medicine, law, religions and the hierarchies of angels and saints.

Otia ImperialiaW
Otia Imperialia

Otia Imperialia is an early 13th-century encyclopedic work, the best known work of Gervase of Tilbury. It is an example of Speculum literature. Also known as the "Book of Marvels", it primarily concerns the three fields of history, geography, and physics, but its credibility has been questioned by numerous scholars including philosopher Gottfried Leibniz, who was alerted to the fact that it contains many mythological stories. Its manner of writing is perhaps because the work was written to provide entertainment to Holy Roman Emperor Otto IV. However, many scholars consider it a very important work in that it "recognizes the correctness of the papal claims in the conflict between Church and Empire." It was written between 1210 and 1214, although some give the dates as between 1209 and 1214 and numerous authors state it was published c.1211.

Speculum literatureW
Speculum literature

The medieval genre of speculum literature, popular from the twelfth through the sixteenth centuries, was inspired by the urge to encompass encyclopedic knowledge within a single work. However, some of these works have a restricted scope and function as instructional manuals. In this sense encyclopedias and speculum are similar but they are not the same genre. Some have suggested that the modern equivalent is a summary survey, in the sense of a survey article in a scholarly journal that summarizes a field of research.

Tree of Science (Ramon Llull)W
Tree of Science (Ramon Llull)

Tree of Science is one of the most extensive and characteristic works of Ramon Llull, written in Rome between 1295 and 1296. It is a version in encyclopaedia format of General Art or Ars magna aimed to non-university public. It has recourse to an analogy common in it: the organic comparison, in which each science is represented by a tree with roots, trunk, branches, leaves and fruits. The roots represent the basic principles of each science; the trunk is the structure; the branches, the genres; the leaves, the species; and the fruits, the individual, his/her acts and his/her finalities. This vegetal allegory shows the influence of Aristotle.
