Wasn't Sertorious the guy that convinced a bunch of people that a deer was the avatar of a goddess, so they should follow him?
Edit: Yes, yes he was..... per wiki

Spanus, one of the commononers who lived in the country came across a doe trying to escape from hunters. The doe fled faster than he could pursue, but the animal had newly given birth. He [Spanus] was struck by the unusual colour of the fawn, for it was pure white. He pursued and caught it.
As it happened, Sertorius was in the area, and it was known that he amply rewarded those who brought him game and produce. So Spanus gave the fawn to Sertorius, who at that time felt only the usual pleasure of one who receives such gift. After a while the animal became so tame and well-trained that it came when he called it, and followed him on his walks without minding the crowds and bustle of life in camp. [That the fawn did this tells us something more about the character of Sertorius.] Eventually it occured to him that the barbarians easily fall into superstition, so he started to give the fawn religious significance. He announced that the doe had been sent by [the goddess] Diana, and solemnly claimed that through the doe she revealed hidden information to him. He helped the idea along by various tricks. If he heard of an enemy raid into his territory, or an attempt to subvert a city from its allegiance to him, he would claim that the fawn had told him of this in a dream, and tell his men to prepare. Or when his commanders sent him messages of victory, he would hide the messenger and bring out the white fawn wearing celebratory garlands. He would sacrifice to the gods, and tell his men to celebrate because they would soon hear something good had happened. By such stratagems he persuaded his people they were not by the fallible wisdom of some foreigner, but by divine power. So the people were made tractable and all the more ready to help him with his plans, and consequently the extraordinary growth of Sertorius's power led to reinforcing this belief.[37]
