Hyginus Fabulae, 165 Marsyas
Minerva is said to have been the first to fashion musical pipes [the tibia] from deer bone and to pipe at the feast of the gods. When Juno and Venus laughed at her, because she was grey-eyed and she blew out her cheeks. She did look hideous and, after the mocking during her song, she fled to the grove on Mt Ida and came to a pool where she watched her reflection piping in the water. She saw that she had deserved to be laughed at. Thereupon she cast away her pipes and begged that anybody who should pick them up be afflicted with a terrible punishment. They were discovered by Marsyas, the son of Oeagrus and a shepherd, one of the satyrs. With the pipes Marsyas practised persistently and came to make more melodious music every day, so much so that he provoked a competition against Apollo playing on the cithara. When Apollo came to this contest, they summoned the Muses to adjudicate. When Marsyas was prepared to walk away as the victor Apollo turned his cithara upside down and his playing was just as good. But, Marsyas was not able to do the same thing on his pipes. And so Apollo gave the defeated Marsyas to a Scythian to tie him to a tree, and the Scythian thinly flayed Marsyas' skin off him. Apollo gave the rest of Marsyas' body to his student Olympus for burial. The river of his blood is called the Marsyas after him.

Hyginus Fabulae, 191 King Midas
King Midas of the Mygdones was the son of Cybele and of Tmolus ... elevated at the time when Apollo contended with Marsyas — or some say with Pan — on the reed-pipe. When Tmolus gave the victory to Apollo, Midas pronounced that the victory should be given to Marsyas instead. Thereupon Apollo angrily said to Midas, "You shall have ears of the same quality as the heart you used in that contest's' judgment." As soon as he delivered this threat, he caused Midas to have the ears of an ass. In those days Father Liber was making war against India and Silenus wandered off. Midas hospitably received him and gave him a guide return Silenus to the band of Liber. So, Father Liber offered in exchange for his kindness the power to choose from him anything he wanted. So, Midas chose that anything he should touch would turn to gold. After choosing this and returning to his royal home, whatever he touched turned to gold. Later when Midas was tormented by starvation, he asked Liber to take from him the pernicious gift. Liber instructed him to bathe in the Pactolus River. When his body touched the water, the water turned golden in color. This river in Lydia is now called the Chrysorrhoas, "the Golden Flows".

     165. Marsyas.
Minerua tibias dicitur prima ex osse ceruino fecisse et ad epulum deorum cantatum uenisse. (2) Iuno et Venus cum eam irriderent, quod et caesia erat et buccas inflaret, foeda uisa et in cantu irrisa in Idam siluam ad fontem uenit, ibique cantans in aqua se adspexit et uidit se merito irrisam; unde tibias abiecit et imprecata est ut quisquis eas sustulisset, graui afficeretur supplicio. (3) quas Marsyas Oeagri filius pastor unus e satyris inuenit, quibus assidue commeletando sonum suauiorem in dies faciebat, adeo ut Apollinem ad citharae cantum in certamen prouocaret. (4) quo ut Apollo uenit, Musas iudices sumpserunt, et cum iam Marsyas inde uictor discederet, Apollo citharam uersabat idemque sonus erat; quod Marsya tibiis facere non potuit. (5) itaque Apollo uictum Marsyan ad arborem religatum Scythae tradidit, qui cutem ei membratim separauit; reliquum corpus discipulo Olympo sepulturae tradidit, e cuius sanguine flumen Marsyas est appellatum.


     191. Rex Midas.
Midas rex Mygdonius filius Matris deae a Timolo . . . . sumptus eo tempore quo Apollo cum Marsya uel Pane fistula certauit. quod cum Timolus uictoriam Apollini daret, Midas dixit Marsyae potius dandam. (2) tunc Apollo indignatus Midae dixit, "Quale cor in iudicando habuisti, tales et auriculas habebis." quibus auditis effecit ut asininas haberet aures. (3) eo tempore Liber pater cum exercitum in Indiam duceret, Silenus aberrauit, quem Midas hospitio liberaliter accepit atque ducem dedit, qui eum in comitatum Liberi deduceret.(4) at Midae Liber pater ob beneficium deoptandi dedit potestatem, ut quicquid uellet peteret a se. a quo Midas petiit ut quicquid tetigisset aurum fieret. quod cum impetrasset et in regiam uenisset, quicquid tetigerat aurum fiebat. (5) cum iam fame cruciaretur, petit a Libero ut sibi speciosum donum eriperet; quem Liber iussit in flumine Pactolo se abluere, cuius corpus aquam cum tetigisset, facta est colore aureo; quod flumen nunc Chrysorrhoas appellatur in Lydia.
