Question: What statue type is the basis for the Mantua statue, of the deity who fathered Oncius?

full_context: Document 1: Discobolus: The Discobolus of Myron ("discus thrower", , "Diskobólos") is a Greek sculpture completed at the start of the Classical Period, figuring a youthful ancient Greek athlete throwing discus, circa 460–450 BC. The original Greek bronze is lost but the work is known through numerous Roman copies, both full-scale ones in marble, which was cheaper than bronze, such as the first to be recovered, the "Palombara Discobolus", and smaller scaled versions in bronze.
Document 2: Apollo: It is also stated that Hera kidnapped Eileithyia, the goddess of childbirth, to prevent Leto from going into labor. The other gods tricked Hera into letting her go by offering her a necklace, nine yards (8 m) long, of amber. Mythographers agree that Artemis was born first and then assisted with the birth of Apollo, or that Artemis was born one day before Apollo, on the island of Ortygia and that she helped Leto cross the sea to Delos the next day to give birth to Apollo. Apollo was born on the seventh day (ἑβδομαγενής, hebdomagenes) of the month Thargelion —according to Delian tradition—or of the month Bysios—according to Delphian tradition. The seventh and twentieth, the days of the new and full moon, were ever afterwards held sacred to him.
Document 3: Apollo: Kouros (male youth) is the modern term given to those representations of standing male youths which first appear in the archaic period in Greece. This type served certain religious needs and was first proposed for what was previously thought to be depictions of Apollo. The first statues are certainly still and formal. The formality of their stance seems to be related with the Egyptian precedent, but it was accepted for a good reason. The sculptors had a clear idea of what a young man is, and embodied the archaic smile of good manners, the firm and springy step, the balance of the body, dignity, and youthful happiness. When they tried to depict the most abiding qualities of men, it was because men had common roots with the unchanging gods. The adoption of a standard recognizable type for a long time, is probably because nature gives preference in survival of a type which has long be adopted by the climatic conditions, and also due to the general Greek belief that nature expresses itself in ideal forms that can be imagined and represented. These forms expressed immortality. Apollo was the immortal god of ideal balance and order. His shrine in Delphi, that he shared in winter with Dionysius had the inscriptions: γνῶθι σεαυτόν (gnōthi seautón="know thyself") and μηδὲν ἄγαν (mēdén ágan, "nothing in excess"), and ἐγγύα πάρα δ'ἄτη (eggýa pára d'atē, "make a pledge and mischief is nigh").
Document 4: Apollo: In literary contexts, Apollo represents harmony, order, and reason—characteristics contrasted with those of Dionysus, god of wine, who represents ecstasy and disorder. The contrast between the roles of these gods is reflected in the adjectives Apollonian and Dionysian. However, the Greeks thought of the two qualities as complementary: the two gods are brothers, and when Apollo at winter left for Hyperborea, he would leave the Delphic oracle to Dionysus. This contrast appears to be shown on the two sides of the Borghese Vase.
Document 5: Pelias: Many years later, Pelias offered a sacrifice by the sea in honor of Poseidon. Jason, who was summoned with many others to take part in the sacrifice, lost one of his sandals in the flooded river Anaurus while rushing to Iolcus. In Virgil's Aeneid, Hera had disguised herself as an old woman, whom Jason was helping across the river when he lost his sandal. When Jason entered Iolcus, he was announced as a man wearing one sandal. Fearful, Pelias asked Jason what he would do if confronted with the man who would be his downfall. Jason responded that he would send that man after the Golden Fleece. Pelias took Jason's advice and sent him to retrieve the Golden Fleece. It would be found at Colchis, in a grove sacred to Ares, the god of war. Though the Golden Fleece simply hung on an oak tree, this was a seemingly impossible task, as an ever - watchful dragon guarded it.
Document 6: Acontius: Acontius (Ancient Greek: Ἀκόντιος), was in Greek mythology a beautiful youth of the island of Ceos, the hero of a love-story told by Callimachus in a poem of which only fragments remain, and which forms the subject of two of Ovid's "Heroides." During the festival of Artemis at Delos, Acontius saw Cydippe, a well-born Athenian maiden of whom he was enamoured, sitting in the temple of the goddess. He wrote on an apple the words, "I swear by Artemis that I will marry Acontius", and threw it at her feet. She picked it up, and mechanically read the words aloud, which amounted to a solemn undertaking to carry them out. Unaware of this, she treated Acontius with contempt; but, although she was betrothed more than once, she always fell ill before the wedding took place. The Delphic oracle at last declared the cause of her illnesses to be the wrath of the offended goddess; whereupon her father consented to her marriage with Acontius. Antoninus Liberalis, tells the story with different names; see Ctesylla.
Document 7: Discobolus: The Discobolus of Myron (``discus thrower '', Greek: Δισκοβόλος, Diskobólos) is a Greek sculpture completed at the start of the Classical Period, figuring a youthful ancient Greek athlete throwing discus, circa 460 -- 450 BC. The original Greek bronze is lost but the work is known through numerous Roman copies, both full - scale ones in marble, which was cheaper than bronze, such as the first to be recovered, the Palombara Discobolus, and smaller scaled versions in bronze.
Document 8: Apollo: It seems an oracular cult existed in Delphi from the Mycenaean ages. In historical times, the priests of Delphi were called Labryaden, "the double-axe men", which indicates Minoan origin. The double-axe, labrys, was the holy symbol of the Cretan labyrinth. The Homeric hymn adds that Apollo appeared as a dolphin and carried Cretan priests to Delphi, where they evidently transferred their religious practices. Apollo Delphinios was a sea-god especially worshiped in Crete and in the islands, and his name indicates his connection with Delphi and the holy serpent Delphyne ("womb").[citation needed] Apollo's sister Artemis, who was the Greek goddess of hunting, is identified with Britomartis (Diktynna), the Minoan "Mistress of the animals". In her earliest depictions she is accompanied by the "Mister of the animals", a male god of hunting who had the bow as his attribute. His original name is unknown, but it seems that he was absorbed by the more popular Apollo, who stood by the virgin "Mistress of the Animals", becoming her brother.
Document 9: Apollo of Mantua: The Apollo of Mantua and its variants are early forms of the Apollo Citharoedus statue type, in which the god holds the cithara in his left arm. The type-piece, the first example discovered, is named for its location at Mantua; the type is represented by neo-Attic Imperial Roman copies of the late 1st or early 2nd century, modelled upon a supposed Greek bronze original made in the second quarter of the 5th century BCE, in a style similar to works of Polyclitus but more archaic. The Apollo held the "cythara" against his extended left arm, of which in the Louvre example ("illustration") a fragment of one twisting scrolling horn upright remains against his biceps.
Document 10: Apollo: As the patron of Delphi (Pythian Apollo), Apollo was an oracular god—the prophetic deity of the Delphic Oracle. Medicine and healing are associated with Apollo, whether through the god himself or mediated through his son Asclepius, yet Apollo was also seen as a god who could bring ill-health and deadly plague. Amongst the god's custodial charges, Apollo became associated with dominion over colonists, and as the patron defender of herds and flocks. As the leader of the Muses (Apollon Musegetes) and director of their choir, Apollo functioned as the patron god of music and poetry. Hermes created the lyre for him, and the instrument became a common attribute of Apollo. Hymns sung to Apollo were called paeans.
Document 11: Apollo: Four days after his birth, Apollo killed the chthonic dragon Python, which lived in Delphi beside the Castalian Spring. This was the spring which emitted vapors that caused the oracle at Delphi to give her prophecies. Hera sent the serpent to hunt Leto to her death across the world. To protect his mother, Apollo begged Hephaestus for a bow and arrows. After receiving them, Apollo cornered Python in the sacred cave at Delphi. Apollo killed Python but had to be punished for it, since Python was a child of Gaia.
Document 12: Nerites (mythology): In the other version, Nerites was loved by Poseidon and answered his feelings. From their mutual love arose Anteros (personification of reciprocated love). Poseidon also made Nerites his charioteer; the boy drove the chariot astonishingly fast, to the admiration of various sea creatures. Helios, for reasons unknown to Aelian's sources, changed Nerites into a shellfish. Aelian himself supposes that Helios might have wanted the boy for himself and was offended by his refusal. As in the first version, Nerea found her brother and successfully persuaded Poseidon to restore Nerites to his true shape.
Document 13: Oncius: In Greek mythology, Oncius (Ancient Greek: Ὅγκιος "Onkios") or Oncus (Ὅγκος "Onkos") was a son of Apollo and a ruler over Onceium (Onkeion), a region of Arcadia adjacent to Thelpusa, as well as eponym of a city Oncae. He owned a herd of horses, in which Demeter tried to hide from Poseidon's advances, changing herself into a mare. Poseidon did mate with her in the shape of a stallion, which resulted in the birth of the fantastic horse Arion. Oncius kept Arion and later gave him away to Heracles as the latter was starting a military campaign against Elis.
Document 14: Apollo: Apollo (Attic, Ionic, and Homeric Greek: Ἀπόλλων, Apollōn (GEN Ἀπόλλωνος); Doric: Ἀπέλλων, Apellōn; Arcadocypriot: Ἀπείλων, Apeilōn; Aeolic: Ἄπλουν, Aploun; Latin: Apollō) is one of the most important and complex of the Olympian deities in classical Greek and Roman religion and Greek and Roman mythology. The ideal of the kouros (a beardless, athletic youth), Apollo has been variously recognized as a god of music, truth and prophecy, healing, the sun and light, plague, poetry, and more. Apollo is the son of Zeus and Leto, and has a twin sister, the chaste huntress Artemis. Apollo is known in Greek-influenced Etruscan mythology as Apulu.
Document 15: Capitoline Venus: The Capitoline Venus is a type of statue of Venus, specifically one of several "Venus Pudica" (modest Venus) types (others include the Venus de' Medici type), of which several examples exist. The type ultimately derives from the Aphrodite of Cnidus. The Capitoline Venus and her variants are recognisable from the position of the arms—standing after a bath, Venus begins to cover her breasts with her right hand, and her groin with her left hand.
