Hyginus Fabulae, 7 Antiope.
Antiope, the daughter of Nycteus, was deceived and raped by Epaphus and was therefore cast off by her husband, Lycus. Jupiter bedded her when she was single. But then Lycus married Dirce, and she began to suspect that her husband had slept secretly with Antiope. Therefore Dirce ordered her slaves to chain her up and enclose her in a cave. When Antiope's time to deliver was near, she fled from her confinement with Jupiter's help and went up on Mount Cithaeron. When the birth was pressing and she sought a place to bear her child, the labor pains compelled her to give birth on the roadside. Shepherds took her twins as their own and called them Zethus — from ἀπὸ τοῦ ζητεῖν τόπον (Greek for "the place to seek") — and Amphion — ὅτι ἐν διόδῳ ἢ ὅτι ἀμφὶ ὁδὸν αὐτὸν ἔτεκεν (Greek for "because she bore him in the crossroads or beside the road") — i.e. since she bore him at the crossroads). And these boys later came to know their mother; they bound Dirce to an uncontrollable bull and killed her. From his body upon Mount Cithaeron a spring of water sprang up, and this is called the Dircaean Spring, a gift of Bacchus (Liber) whose bacchante Antiope had been.

8. The Antiope of Euripides, which Ennius adapted:
Antiope was the daughter of Nycteus, the king of Boeotioa. Jupiter was attracted by the physical beauty and impregnated her. When her father took measures to punish her for rape and threatened to endanger her, Antiope escaped. By chance in that same place where she had escaped to Ephaphus the Sicyonian was staying. He took her to himself as his wife and bound himself to her in marriage. Nycteus was angry. When he implored him that he should stay with his brother Lycus and then offered him his kingdom to keep Antiope safe. After his death, Lycus came to Sicyon. Epaphus was murdered and Nycteus bound Antiope and took her onto Mount Cithaeron. She gave birth to twins and left them for a shepherd to raise. He called them Zetus and Amphion. Antiope was given to Dirce, Lycus' wife, for execution. But, having acquired an opportunity by chance, she escaped and came to find her sons. Zetus, one of her sons, considered her a refugee and did not take her in. Dirce was celebrating the rites of Bacchus (Liber) and happened to come to the spot. She started to drag Antiope off for death, but her sons were informed by the shepherd (who was their tutor) that she was their mother. They went in quick pursuit and saved their mother. They tied Dirce by her hair to a bull. When they desired also to murder Lycus also, Mercury stopped them and at the same time ordered Lycus to yield his kingdom to Amphion.

antiopa.
Antiopa Nyctei filia ab Epapho per dolum est stuprata, itaque a Lyco uiro suo eiecta est. hanc uiduam Iuppiter compressit. (2) at Lycus Dircen in matrimonium duxit, cui suspicio incidit uirum suum clam cum Antiopa concubuisse; itaque imperauit famulis ut eam in tenebris uinctam clauderent. (3) cui postquam partus instabat, effugit ex uinculis Iouis uoluntate in montem Cithaeronem; cumque partus premeret et quaereret ubi pareret, dolor eam in ipso biuio coegit partum edere. (4) quos pastores pro suis educarunt et appellarunt Zeton, ἀπὸ τοῦ ζητεῖν τόπον, alterum uero Amphionem, ὅτι ἐν διόδῳ ἢ ὅτι ἀμφὶ ὁδὸν αὐτὸν ἔτεκεν, id est quoniam in biuio eum edidit. (5) qui postquam matrem agnouerunt, Dircen ad taurum indomitum deligatam uita priuarunt, ex cuius corpore in monte Cithaerone fons est natus qui Dircaeus est appellatus, beneficio Liberi, cuius baccha fuerat.

8 [Antiope] Euripidis (quam scribit Ennius). Nyctei regis in Boeotia fuit filia Antiopa; eius formae bonitate Iuppiter adductus grauidam fecit. (2) quam pater cum punire uellet propter stuprum minitans periculum, Antiopa effugit. casu in eodem loco quo illa peruenerat Epaphus Sicyonius stabat; is mulierem aduectam domo matrimonio suo iunxit. (3) id Nycteus aegre ferens, cum moreretur Lyco fratri suo per obtestationem mandat, cui tum regnum relinquebat, ne impune Antiopa ferret; huius post mortem Lycus Sicyonem uenit; interfecto Epapho Antiopam uinctam adduxit in Cithaeronem; parit geminos et reliquit, quos pastor educauit, Zetum et Amphionem nominauit.(4) Antiopa Dirce uxori Lyci data erat in cruciatum; ea occasione nacta fugae se mandauit; deuenit ad filios suos, ex quibus Zetus existimans fugitiuam non recepit. in eundem locum Dirce per bacchationem Liberi illuc delata est; ibi Antiopam repertam ad mortem extrahebat. (5) sed ab educatore pastore adulescentes certiores facti eam esse matrem suam, celeriter consecuti matrem eripuerunt, Dircen ad taurum crinibus religatam necant.(6) Lycum cum occidere uellent, uetuit eos Mercurius, et simul iussit Lycum concedere regnum Amphioni.
