[...]There is an animal called the hyena, which inhabits the tombs of the dead and feeds on their bodies. Its nature is that it is sometimes male, sometimes female, and it is therefore an unclean animal. Since its spine is rigid, all in one piece, it cannot turn round except by turning its body right around. Solinus recounts many marvellous things about the hyena. First, it stalks the sheepfolds of shepherds and circles their houses by night, and by listening carefully learns their speech, so that it can imitate the human voice, in order to fall on any man whom it has lured out at night. The hyena also [imitates] human vomit and devours the dogs it has enticed with faked sounds of retching. If dogs hunting the hyena accidentally touch its shadow behind, they lose their voices and cannot bark. In its search for buried bodies, the hyena digs up graves. The sons of Israel resemble the hyena. At the beginning they served the living God. Later, addicted to wealth and luxury, they worshipped idols. For this reason the prophet compared the synagogue to an unclean animal: 'My heritage is to me as the den of a hyena.' (see Jeremiah, 12:8) Therefore those among us who are slaves to luxury and greed, are like this brute, since they are neither men nor women, that is, neither faithful nor faithless, but are without doubt those of whom Solomon says: 'A double-minded man is unstable in all his ways'; (James, 1:8) of whom the Lord says: 'You cannot serve God and mammon.' (Matthew, 6:24) [...]
