Diogenes of Apollonia (/daɪˈɒdʒɪniːz/ dy-OJ-in-eez; Ancient Greek: Διογένης ὁ Ἀπολλωνιάτης, romanized: Diogénēs ho Apollōniátēs; fl. 5th century BC) was an ancient Greek philosopher, and was a native of the Milesian colony Apollonia in Thrace. He lived for some time in Athens. He believed air to be the one source of all being from which all other substances were derived, and, as a primal force, to be both divine and intelligent. He also wrote a description of the organization of blood vessels in the human body. His ideas were parodied by the dramatist Aristophanes, and may have influenced the Orphic philosophical commentary preserved in the Derveni papyrus. His philosophical work has not survived in a complete form, and his doctrines are known chiefly from lengthy quotations of his work by Simplicius, as well as a few summaries in the works of Aristotle, Theophrastus, and Aetius.
