Franciscan friar in the context of "Order of Saint Clare"

William of Ockham or Occam OFM (/ˈɒkəm/ OK-əm; Latin: Gulielmus Occamus; c. 1287 – 9/10 April 1347) was an English Franciscan friar, scholastic philosopher, apologist, and theologian, who was born in Ockham, a small village in Surrey. He is considered to be one of the major figures of medieval thought and was at the centre of the major intellectual and political controversies of the 14th century. He is widely known for Occam's razor, the methodological principle that bears his name, and also produced significant works on logic, physics and theology. Ockham is remembered in the Church of England with a commemoration corresponding to the commonly ascribed date of his death on 10 April.

John Duns Scotus OFM (/ˈskoʊtəs/ SKOH-təs; Ecclesiastical Latin: [duns ˈskɔtus], "Duns the Scot"; c. 1265/66 – 8 November 1308) was a Scottish Catholic priest and Franciscan friar, university professor, philosopher and theologian. He is considered among the most important philosopher-theologians in Western Christendom during the last part of the medieval period, together with Thomas Aquinas, Bonaventure and William of Ockham.

Duns Scotus has had considerable influence on both Catholic and secular thought. The doctrines for which he is best known are the "univocity of being", that existence is the most abstract concept we have, applicable to everything that exists; the formal distinction, a way of distinguishing between different formalities of the same thing; and the idea of haecceity, the property supposed to be in each individual thing that makes it an individual (i.e. a certain "thisness"). Duns Scotus also developed a complex argument for the existence of God, and argued for the Immaculate Conception of Mary. The intellectual tradition derived from Scotus' work is called Scotism.

The Florentine Codex is a 16th-century ethnographic research study in Mesoamerica by the Spanish Franciscan friar Bernardino de Sahagún. Sahagún originally titled it La Historia General de las Cosas de Nueva España (in English: The General History of the Things of New Spain). After a translation mistake, it was given the name Historia general de las Cosas de Nueva España. The best-preserved manuscript is commonly referred to as the Florentine Codex, as the codex is held in the Laurentian Library of Florence, Italy.

In partnership with Nahua elders and authors who were formerly his students at the Colegio de Santa Cruz de Tlatelolco, Sahagún conducted research, organized evidence, wrote and edited his findings. He worked on this project from 1545 up until his death in 1590. The work consists of 2,500 pages organized into twelve books; more than 2,000 illustrations drawn by native artists provide vivid images of this era. It documents the culture, religious cosmology (worldview) and ritual practices, society, economics, and natural history of the Aztec people. It has been described as "one of the most remarkable accounts of a non-Western culture ever composed."
