Lucian De Sacrificiis 13

[13] And although the notice says that no one is to be allowed within the holy-water who has not clean hands, the priest himself stands there all bloody, just like the Cyclops of old, cutting up the victim, removing the entrails, plucking out the heart, pouring the blood about the altar, and doing everything possible in the way of piety. To crown it all, he lights a fire and puts upon it the goat, skin and all, and the sheep, wool and all; and the smoke, divine and holy, mounts upward and gradually dissipates into Heaven itself.

The Scythians, indeed, reject all the sacrificial animals and think them too mean; they actually offer men to Artemis and by so doing gratify the goddess!

[13] According to the proclamation, no man shall approach the holy ground with unclean hands, Yet there stands the priest himself, wallowing in gore; handling his knife like a very Cyclops, drawing out entrails and heart, sprinkling the altar with blood,—in short, omitting no detail of his holy office. Finally, he kindles fire, and sets the victim bodily thereon, sheep or goat, unfleeced, unflayed. A godly steam, and fit for godly nostrils, rises heavenwards, and drifts to each quarter of the sky. The Scythian, by the way, will have nothing to do with paltry cattle: he offers men to Artemis; and the offering is appreciated.
