By his neesings a light doth shine - It is very likely that this may be taken literally. When he spurts up the water out of his nostrils, the drops form a sort of iris or rainbow. We have seen this effect produced when, in certain situations and state of the atmosphere, water was thrown up forcibly, so as to be broken into small drops, which has occasioned an appearance like the rainbow.

The eyelids of the morning - It is said that, under the water, the eyes of the crocodile are exceedingly dull; but when he lifts his head above water they sparkle with the greatest vivacity. Hence the Egyptians, in their hieroglyphics, made the eyes of the crocodile the emblem of the morning. Ανατολην λεγοντες δυο οφθαλμους κροκοδειλου ζωογραφουσι. - Horapp. Egypt. Ieroglyph., lib. i., c. 65. This is a most remarkable circumstance, casts light on ancient history, and shows the rigid correctness of the picture drawn above. The same figure is employed by the Greek poets.

Whether the Devil Can Induce Man to Sin of Necessity?
Objection 1: It would seem that the devil can induce man to sin of necessity. Because the greater can compel the lesser. Now it is said of the devil (Job 41:24) that "there is no power on earth that can compare with him." Therefore he can compel man to sin, while he dwells on the earth. Objection 2: Further, man's reason cannot be moved except in respect of things that are offered outwardly to the senses, or are represented to the imagination: because "all our knowledge arises from the senses, and …

How Sowers of Strifes and Peacemakers are to be Admonished.
(Admonition 24.) Differently to be admonished are sowers of strifes and peacemakers. For sowers of strifes are to be admonished to perceive whose followers they are. For of the apostate angel it is written, when tares had been sown among the good crop, An enemy hath done this (Matth. xiii. 28). Of a member of him also it is said through Solomon, An apostate person, an unprofitable man, walketh with a perverse mouth, he winketh with his eyes, he beateth with his foot, he speaketh with his finger, …

Whether Wisdom Should be Reckoned among the Gifts of the Holy Ghost?
Objection 1: It would seem that wisdom ought not to be reckoned among the gifts of the Holy Ghost. For the gifts are more perfect than the virtues, as stated above ([2705]FS, Q[68], A[8]). Now virtue is directed to the good alone, wherefore Augustine says (De Lib. Arb. ii, 19) that "no man makes bad use of the virtues." Much more therefore are the gifts of the Holy Ghost directed to the good alone. But wisdom is directed to evil also, for it is written (James 3:15) that a certain wisdom is "earthly, …
