The Motherless Birth of Pallas Athena: Apollodorus, Bibl.1.3.6

Name: [Pseudo]Apollodorus Date:   1st – 2nd century CE Region:    Unknown Citation:    Library 1.3.6

Thetis tried to escape Jupiter's seduction by changing forms, but was unsuccessful. When she became pregnant, Jupiter swallowed her whole, fearing a prophecy that claimed that after she birthed a daughter, she would bear a son who would rule the universe.
When the time had come for the child's delivery, Prometheus (or Vulcan, as others say), struck Jupiter's head with an ax, and Pallas Athena sprang forth from the wound fully armed.
 

μίγνυται δὲ Ζεὺς Μήτιδι, μεταβαλλούσῃ εἰς πολλὰς ἰδέας ὑπὲρ τοῦ μὴ συνελθεῖν, καὶ αὐτὴν γενομένην ἔγκυον καταπίνει φθάσας, ἐπείπερ ἔλεγε Γῆ γεννήσειν παῖδα μετὰ τὴν μέλλουσαν ἐξ αὐτῆς γεννᾶσθαι κόρην, ὃς οὐρανοῦ δυνάστης γενήσεται. τοῦτο φοβηθεὶς κατέπιεν αὐτήν: ὡς δ᾽ ὁ τῆς γεννήσεως ἐνέστη χρόνος, πλήξαντος αὐτοῦ τὴν κεφαλὴν πελέκει Προμηθέως ἢ καθάπερ ἄλλοι λέγουσιν Ἡφαίστου, ἐκ κορυφῆς, ἐπὶ ποταμοῦ Τρίτωνος, Ἀθηνᾶ σὺν ὅπλοις ἀνέθορεν.
Jupiter ad haec Thetidi, varias alternanti formas quo illius vitaret amplexus, immiscetur. Quam, cum gravidam esse persensisset, absorbere occupat, quoniam post natam ex ea puellam, filium se parituram dicebat, qui caeli dominatione potiturus esset. Id futurum veritus eam absorbuit. Ubi vero pariendi tempus advenit, Prometheus, sive, ut alii tradunt, Volcanus eius caput securi percussit, deque illius vertice secus Tritonem amnem armata Pallas exilivit.
