Apollonius of Chalcedon was an ancient Greek Stoic who taught philosophy. He was invited by the Roman emperor Antoninus Pius to come to Rome, for the purpose of instructing his adoptive sons Marcus Aurelius and Lucius Verus in philosophy. Aurelius, within his Meditations, writes of Apollonius favourably. Lucian writes of him:When Apollonius was appointed professor of philosophy in the Imperial household, Demonax witnessed his departure, attended by a great number of his pupils. 'Why, here is Apollonius with all his Argonauts,' he cried.
Apollonius of Perga was an ancient Greek geometer and astronomer known for his work on conic sections. Beginning from the earlier contributions of Euclid and Archimedes on the topic, he brought them to the state prior to the invention of analytic geometry. His definitions of the terms ellipse, parabola, and hyperbola are the ones in use today. With his predecessors Euclid and Archimedes, Apollonius is generally considered among the greatest mathematicians of antiquity.
Apollonius of Rhodes was an ancient Greek author, best known for the Argonautica, an epic poem about Jason and the Argonauts and their quest for the Golden Fleece. The poem is one of the few extant examples of the epic genre and it was both innovative and influential, providing Ptolemaic Egypt with a "cultural mnemonic" or national "archive of images", and offering the Latin poets Virgil and Gaius Valerius Flaccus a model for their own epics. His other poems, which survive only in small fragments, concerned the beginnings or foundations of cities, such as Alexandria and Cnidus places of interest to the Ptolemies, whom he served as a scholar and librarian at the Library of Alexandria. A literary dispute with Callimachus, another Alexandrian librarian/poet, is a topic much discussed by modern scholars since it is thought to give some insight into their poetry, although there is very little evidence that there ever was such a dispute between the two men. In fact almost nothing at all is known about Apollonius and even his connection with Rhodes is a matter for speculation. Once considered a mere imitator of Homer, and therefore a failure as a poet, his reputation has been enhanced by recent studies, with an emphasis on the special characteristics of Hellenistic poets as scholarly heirs of a long literary tradition writing at a unique time in history.
Apollonius of Tyana was a Greek Neopythagorean philosopher from the town of Tyana in the Roman province of Cappadocia in Anatolia. He is the subject of Life of Apollonius of Tyana, written by Philostratus over a century after his death.
