Editing Adelard of Bath (section)

== Influence ==
Adelard's work impacted the course of natural philosophy, notably influencing [[Robert Grosseteste]] and [[Roger Bacon]].<ref>Gracia, Jorge J. E. and Timothy B. Noone (eds.). A Companion to Philosophy in the Middle Ages (Malden, MA: Blackwell, 2003)</ref> His work in natural philosophy helped lay the foundations for much of the progress that was made in the later centuries after [[Aristotle]]. His work surrounding Euclid's ''Elements'' provided training in demonstrative and geometrical proofs. While his original writings demonstrate a sincere passion for the seven liberal arts (grammar, rhetoric, logic, mathematics, geometry, music, and astronomy), his work in ''Quaestiones naturales'' illustrated a more encompassing dedication to subjects such as [[physics]], the [[natural science]]s, and [[metaphysics]].

His influence is evident in ''De philosophia mundi'' by [[William of Conches]],<ref>{{Cite book |last=Morton |first=Jonathan |title=Making Sense of ingenium: Translating Thought in Twelfth-Century Latin Texts on Cognition |publisher=Routledge |year=2022 |isbn=9781003258704 |edition=1st |pages=97, 99 |language=English}}</ref> in the work of [[Hugh of Saint Victor]], in [[Isaac of Stella]]'s ''Letters to Alcher on the Soul'' and in [[Peter Abelard]]'s ''Hexaemeron''.

He introduced algebra to the Latin world and his commentaries in Euclid's ''Elements'' were extremely influential in the 13th century.<ref name="hackett"/> Adelard was also responsible for introducing Arabic numerals, including the symbol for zero, to Western Europe.<ref name=":0"/> Adelard displayed original thought of a scientific bent, questioning the shape of the Earth (he believed it was round) and asking how it remains stationary in space. He developed the classic physics question of how far a rock would fall if a hole were drilled through the Earth and a rock dropped through it (see [[center of gravity]]). He later supplemented his mathematical translations with "De opere astrolapsus," a text explaining the use of an astrolabe.<ref name=":0"/>

[[Campanus of Novara]] probably had access to Adelard's translation of ''Elements'', and it is Campanus' edition that was first published in [[Venice]] in 1482 after the invention of the [[printing press]]. It became the chief [[textbook]] of the mathematical schools of Western Europe until the 16th century.<ref>see Hannam (2009) p67.</ref>
