Daria Semegen (born June 27, 1946) is a contemporary American composer of classical music.
 While she has composed pieces for traditional instruments — her "Jeux des quatres" (1970), for example, is scored for clarinet, trombone, cello, and piano — she is best known as a "respected electronic composer."
 She is a figure on the academic side of the electronic music genre, connected with the conservatory and the university (like her older contemporary Karlheinz Stockhausen), rather than the more popular expression of the genre that followed upon the widespread availability of synthesizers and personal computers in the 1970s and after.
 Her writing covers a range of topics related to musical composition and has been the subject of studies by other scholars.

Apollonius of Rhodes (Ancient Greek: Ἀπολλώνιος Ῥόδιος "Apollṓnios Rhódios"; Latin: "Apollonius Rhodius" ; fl.
 first half of 3rd century BCE), 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 Cnidusplaces 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.
