251. The reason why the “serpent” means all evil in general, and specifically the love of self, is that all evil has had its rise from that sensuous part of the mind, and also from that memory-knowledge [scientifico], which at first were signified by the “serpent;” and therefore it here denotes evil of every kind, and specifically the love of self, or hatred against the neighbor and the Lord, which is the same thing. As this evil or hatred was various, consisting of numerous genera and still more numerous species, it is described in the Word by various kinds of serpents, as “snakes” “cockatrices” “asps” “adders” “fiery serpents” “serpents that fly” and “that creep” and “vipers” according to the differences of the poison, which is hatred. Thus we read in Isaiah:

Rejoice not thou, whole Philistia, because the rod which smiteth thee is broken, for out of the serpent’s root shall go forth a cockatrice, and his fruit shall be a flying fire-serpent (Isaiah 14:29).The “serpent’s root” denotes that part of the mind, or that principle, which is connected with the senses and with memory-knowledge [est sensuale et scientificum]; the “cockatrice” denotes evil originating in the falsity thence derived; and the “flying fire-serpent” the cupidity that comes from the love of self. By the same Prophet also similar things are elsewhere thus described:

They hatch cockatrice’s eggs, and weave the spider’s web; he that eateth of their eggs dieth, and when it is crushed there cometh out a viper (Isaiah 59:5).

The serpent described here in Genesis is called in the Revelation the “great and red dragon” and the “old serpent” and also the “devil and satan” that “deceives the whole world” (Revelation 12:3, 9; 20:2), where, and also in other places, by the “devil” is not meant any particular devil who is prince over the others, but the whole crew of evil spirits, and evil itself.

305. And another horse, fiery red, went out. (6:4) This symbolizes an understanding of the Word among them extinguished as to goodness and thus extinguished as regards their life.

A horse symbolizes an understanding of the Word (no. 298), and a fiery red color symbolizes good extinguished. To be shown that the color white is predicated of truths, because it takes its origin from the light of the sun in heaven, and that the color red is predicated of goods, because it takes its origin from the fire of the sun in heaven, see nos. 167, 231 above.

A fiery red, on the other hand, is predicated of good extinguished, because a fiery red means a hellish red, which takes its origin from hellfire, which is a love of evil. A fiery red, being a hellish red, is hideous and dreadful, because it has no spark of life in it, but is totally lifeless. So it is that a fiery red horse symbolizes an understanding of the Word extinguished as to goodness. This, too, can be seen from the description of its rider, that it was granted him "to take peace from the earth, so that people might kill one another," as said next.

Moreover, it was the second living creature, which was like a calf, symbolizing the Divine truth of the Word in respect to its affection (no. 242), that said, "Come and see," thus showing that the people described had no affection for good, thus no goodness, among them.

That redness is predicated of both a love of good and a love of evil, can be seen from the following passages:

Who... washed his garment in wine, and his vesture in the blood of grapes, with eyes redder than wine, and teeth whiter than milk. (Genesis 49:11-12)

This is said in reference to the Lord.

Who is this who comes from Edom..., red as to apparel, and apparel like that of one who treads in the winepress? (Isaiah 63:1-2)

This, too, said in reference to the Lord.

Her Nazirites were whiter than snow and brighter white than milk. Redder were they in their bones than rubies... (Lamentations 4:7)

Redness in these places is predicated of a love of good. In the following places it is predicated of a love of evil:

The shield... is made reddish, and the... men are in crimson. The chariots come with flaming torches...; their appearance is like that of torches... (Nahum 2:3-4)

Though your sins have been like scarlet, they shall be as white as snow; though they have been red like crimson, they shall be as wool. (Isaiah 1:18)

This is also the symbolic meaning of the fiery red dragon in Revelation 12:3, and of the fiery red horse standing among the myrtle trees in Zechariah 1:8.

Similar meanings are predicated of colors that derive their hue from the color red, such as scarlet and crimson.
