Reference for Sanhedrin 109:14

אלא מעתה עובד כוכבים המשתחוה לבהמתו תיתסר ומקטלא מי איכא מידי דלישראל לא אסר ולעובד כוכבים אסר

It was asked of R. Shesheth: What if a heathen committed bestiality [is the animal killed or not]? Must it have been both a stumbling block and a cause of degradation [in order for it to be stoned], but here it was only a stumbling block, but not a cause of degradation;<span class="x" onmousemove="('comment',' Because bestiality was not unusual among the heathens, therefore he would not feel himself disgraced. This Talmudic judgment on heathen morals may appear very harsh and prejudiced, yet it is not a malicious slander. In the Gilgamesh epic Ebani, the primitive man, lives a wild life with the animals and satisfies his lust with them. Bestiality seems to have been prevalent among the Greeks and Romans of a later period, as is proved by an extremely unsavoury adventure described in the Metamorphoses of Apuleius. Cf. 'A. Z. 22a, which forbids the stabling of cows with heathens, for fear of bestiality. (Hast. Dict. s.v. Bestiality.) ');">¹³</span>
