4.78.2
As time passed, Ariapithes was treacherously killed by Spargapithes, king of the Agathyrsi, and Scyles inherited the kingship and his father's wife, a Scythian woman whose name was Opoea, and she bore Scyles a son, Oricus.
4.78.3
So Scyles was king of Scythia; but he was in no way content with the Scythian way of life, and was much more inclined to Greek ways, from the upbringing that he had received. So this is what he would do: he would lead the Scythian army to the city of the Borysthenites (who say that they are Milesians), and when he arrived there would leave his army in the suburb of the city,
4.78.4
while he himself, entering within the walls and shutting the gates, would take off his Scythian apparel and put on Greek dress; and in it he would go among the townsfolk unattended by spearmen or any others (who would guard the gates, lest any Scythian see him wearing this apparel), and in every way follow the Greek manner of life, and worship the gods according to Greek usage.
4.78.5
When he had spent a month or more like this, he would put on Scythian dress and leave the city. He did this often; and he built a house in Borysthenes, and married a wife of the people of the country and brought her there.

But when things had to turn out badly for him, they did so for this reason: he conceived a desire to be initiated into the rites of the Bacchic Dionysus; and when he was about to begin the sacred mysteries, he saw the greatest vision.
4.79.2
He had in the city of the Borysthenites a spacious house, grand and costly (the same house I just mentioned), all surrounded by sphinxes and griffins worked in white marble; this house was struck by a thunderbolt. And though the house burnt to the ground, Scyles none the less performed the rite to the end.
4.79.3
Now the Scythians reproach the Greeks for this Bacchic revelling, saying that it is not reasonable to set up a god who leads men to madness.
4.79.4
So when Scyles had been initiated into the Bacchic rite, some one of the Borysthenites scoffed at the Scythians: “You laugh at us, Scythians, because we play the Bacchant and the god possesses us; but now this deity has possessed your own king, so that he plays the Bacchant and is maddened by the god. If you will not believe me, follow me now and I will show him to you.”
4.79.5
The leading men among the Scythians followed him, and the Borysthenite brought them up secretly onto a tower; from which, when Scyles passed by with his company of worshippers, they saw him playing the Bacchant; thinking it a great misfortune, they left the city and told the whole army what they had seen.
ch. 80
4.80.1
After this Scyles rode off to his own place; but the Scythians rebelled against him, setting up his brother Octamasades, son of the daughter of Teres, for their king.
4.80.2
Scyles, learning what had happened concerning him and the reason why it had happened, fled into Thrace; and when Octamasades heard this he led his army there. But when he was beside the Ister, the Thracians barred his way; and when the armies were about to engage, Sitalces sent this message to Octamasades:
4.80.3
“Why should we try each other's strength? You are my sister's son, and you have my brother with you; give him back to me, and I will give up your Scyles to you; and let us not endanger our armies.”
4.80.4
Such was the offer Sitalces sent to him; for Sitalces' brother had fled from him and was with Octamasades. The Scythian agreed to this, and took his brother Scyles, giving up his own uncle to Sitalces.
4.80.5
Sitalces then took his brother and carried him away, but Octamasades beheaded Scyles on the spot. This is how closely the Scythians guard their customs, and these are the penalties they inflict on those who add foreign customs to their own.
