Joannes Stobaeus (dʒoʊˈænᵻs_stoʊˈbiːəs; Ἰωάννης ὁ Στοβαῖος; fl. 5th-century AD), from Stobi in Macedonia, was the compiler of a valuable series of extracts from Greek authors. The work was originally divided into two volumes containing two books each. The two volumes became separated in the manuscript tradition, and the first volume became known as the Extracts (also Eclogues) and the second volume became known as the Anthology (also Florilegium). Modern editions now refer to both volumes as the Anthology. The Anthology contains extracts from hundreds of writers, especially poets, historians, orators, philosophers and physicians. The subjects range from natural philosophy, dialectics, and ethics, to politics, economics, and maxims of practical wisdom. The work preserves fragments of many authors and works which otherwise might be unknown today. Nothing of his life is known. The age in which he lived cannot be fixed with accuracy. He quotes no writer later than the early 5th century, and he probably lived around this time. His surname apparently indicates that he was a native of Stobi in Macedonia Salutaris, while his given name, John, would probably indicate that he was a Christian, or at least the son of Christian parents, However, from his silence in regard to Christian authors, it has also been inferred that he was not a Christian. Stobaeus' anthology is a collection of extracts from earlier Greek writers, which he collected and arranged, in the order of subjects, as a repertory of valuable and instructive sayings. The extracts were intended by Stobaeus for his son Septimius, and were preceded by a letter briefly explaining the purpose of the work and giving a summary of the contents. The full title, according to Photius, was Four Books of Extracts, Sayings and Precepts (Ἐκλογῶν, ἀποφθεγμάτων, ὑποθηκῶν βιβλία τέσσαρα [Eklogon, apophthegmaton, hypothekon biblia tessara]). He quoted more than five hundred writers, generally beginning with the poets, and then proceeding to the historians, orators, philosophers, and physicians.
