the muse of orpheus.

According to Apollodorus[18] and a fragment of Pindar,[19] Orpheus's father was Oeagrus, a Thracian king; or, according to another version of the story, the god Apollo. His mother was the muse Calliope; or, a daughter of Pierus,[20] son of Makednos. His birthplace and place of residence was in Pimpleia,[21][22][23] Olympus. In Argonautica the location of Oeagrus and Calliope's wedding is close to Pimpleia,[24] near Olympus.[25][26] While living with his mother and her eight beautiful sisters in Parnassus,[27] he met Apollo, who was courting the laughing muse Thalia. Apollo became fond of Orpheus and gave him a little golden lyre and taught him to play it. Orpheus's mother taught him to make verses for singing. Strabo mentions that he lived in Pimpleia.[25] He is also said to have studied in Egypt.[28]

Orpheus is said to have established the worship of Hecate in Aegina.[29] In Laconia Orpheus is said to have brought the worship of Demeter Chthonia[30] and that of the Kores Sōteiras (Greek,Κόρες Σωτείρας) savior maid.[clarification needed][31] Also in Taygetus a wooden image of Orpheus was said to have been kept by Pelasgians in the sanctuary of the Eleusinian Demeter.[32]

In Greek mythology, Calliope ( /kəˈlaɪ.əpiː/ kə-ly-ə-pee; Ancient Greek: Καλλιόπη Kalliope "beautiful-voiced") was the muse of epic poetry,[1] daughter of Zeus and Mnemosyne, and is now best known as Homer's muse, the inspiration for the Odyssey and the Iliad.

One account says Calliope was the lover of the war god Ares, and bore him several sons: Mygdon, Edonus, Biston, and Odomantus (or Odomas), respectively the founders of Thracian tribes known as the Mygdones, Edones, Bistones, and Odomantes.

Calliope also had two famous sons, Orpheus[2] and Linus,[3] by either Apollo or the king Oeagrus of Thrace. She taught Orpheus verses for singing.[4] She was the wisest of the Muses, as well as the most assertive. She married Oeagrus close to Pimpleia,[5] Olympus.

Calliope is always seen with a writing tablet in her hand. At times, she is depicted as carrying a roll of paper or a book or as wearing a gold crown.

Muse of comedy and idyllic poetry, Jean-Marc NattierThalia /θəˈlaɪə/ (Ancient Greek: Θάλεια, Θαλία; "the joyous, the flourishing", from Ancient Greek: θάλλειν, thállein; "to flourish, to be verdant") was the Muse who presided over comedy and idyllic poetry. In this context her name means "flourishing", because the praises in her songs flourish through time.[1] She was the daughter of Zeus and Mnemosyne, the eighth-born of the nine Muses.

According to pseudo-Apollodorus, she and Apollo were the parents of the Corybantes.[2] Other ancient sources, however, gave the Corybantes different parents.[3]

She was portrayed as a young woman with a joyous air, crowned with ivy, wearing boots and holding a comic mask in her hand. Many of her statues also hold a bugle and a trumpet (both used to support the actors' voices in ancient comedy), or occasionally a shepherd’s staff or a wreath of ivy.
