Editing Galen (section)

===Later years===
Galen continued to work and write in his final years, finishing treatises on drugs and remedies as well as his compendium of diagnostics and therapeutics, which would have much influence as a medical text both in the [[Science in the middle ages|Latin Middle Ages]] and [[Islamic Golden Age|Medieval Islam]].<ref name=":0">{{Citation|last=Hankinson|first=R.

The 11th-century ''[[Suda]]'' lexicon states that Galen died at the age of 70, which would place his death in about the year 199. However, there is a reference in Galen's treatise ''"On Theriac to Piso"'' (which may, however, be spurious) to events of 204. There are also statements in Arabic sources<ref>Amari, M. Biblioteca Arabo-sicula, 2nd vol., Loscher, Turin, Rome, pp. 503–504.</ref> that he died in Sicily at age 87, after 17 years studying medicine and 70 practicing it, which would mean he died about 216. According to these sources, the tomb of Galenus in [[Palermo]] was still well preserved in the tenth century.
