Alexander Ivanovich Odoevsky was a Russian poet and playwright, one of the leading figures of the 1825 Decembrist revolt. One of Odoevsky's lines, "Iz iskry vozgoritsa plamya", has come down in history as a long-lasting slogan of the Russian revolutionary movement. It was chosen as a motto for the Lenin-founded newspaper Iskra, also giving the magazine its title, which means "spark".
Alexander of Aegae was a Peripatetic philosopher who flourished in Rome in the 1st century AD, and was a disciple of the celebrated mathematician Sosigenes of Alexandria.

Attempts in the 19th century to ascribe some of the works of Alexander of Aphrodisias to Alexander of Aegae have been shown to be mistaken.
Alexander of Aphrodisias was a Peripatetic philosopher and the most celebrated of the Ancient Greek commentators on the writings of Aristotle. He was a native of Aphrodisias in Caria and lived and taught in Athens at the beginning of the 3rd century, where he held a position as head of the Peripatetic school. He wrote many commentaries on the works of Aristotle, extant are those on the Prior Analytics, Topics, Meteorology, Sense and Sensibilia, and Metaphysics. Several original treatises also survive, and include a work On Fate, in which he argues against the Stoic doctrine of necessity; and one On the Soul. His commentaries on Aristotle were considered so useful that he was styled, by way of pre-eminence, "the commentator".
