Victorinus of Poetovio
"And I saw a beast coming up out of the sea, like a leopard." This means that the kingdom of that time, the kingdom of Antichrist, will be mixed with a multitude of peoples and men. Its feet are like a bear's, that is, like a strong and most unclean animal. He said that its feet are its leaders. Its mouth is like the mouth of a lion, that is, armed with teeth and flowing blood. For the mouth is his command and his tongue, which in the future will be needed only to shed blood.
