'''''De Gradibus''''' was an [[Arabic language|Arabic]] book published by the Arab physician [[Al-Kindi]] (c. 801–873 CE). ''De gradibus'' is the [[Latinization (literature)|Latinized]] name of the book. An alternative name for the book was '''''Quia Primos'''''.<ref name=Plinio-19>p. 19, [http://www.ishim.net/ishimj/2/03.pdf "Al-Kindi, A Precursor Of The Scientific Revolution"], Plinio Prioreschi, ''Journal of the International Society for the History of Islamic Medicine'' '''1''', #2 (October 2002), pp. 17–19.</ref>

In ''De Gradibus'', Al-Kindi attempts to apply [[mathematics]] to [[pharmacology]] by quantifying the strength of drugs. According to Prioreschi, this was the first attempt at serious quantification in medicine.<ref name=Plinio-18>p. 18, Prioreschi 2002.</ref> During the [[Latin translations of the 12th century|Arabic-Latin translation movement of the 12th century]], ''De Gradibus'' was translated into [[Latin]] by [[Gerard of Cremona]].<ref name=Plinio-19/> Al-Kindi's mathematical reasoning was complex and hard to follow; [[Roger Bacon]] commented that his method of computing the strength of a drug was extremely difficult to use.<ref name=Plinio-18 />
