(trī`dənt), in Greek mythology, three-pronged fork borne by Poseidon. It was variously represented as a fishing spear, a goad, or forked lightning.


(religion, spiritualism, and occult)

The trident is the alchemical sign for water, from its association with Poseidon, Greek god of the sea and creator of waters. Son of Kronos and Rhea, and brother of Zeus, Poseidon split the earth with his trident, earning himself the title "Earth Shaker," according to Homer.

In India, Shiva was trident-bearer to Kali. Originally thought of as a triple phallus, the trident has come to be associated with Satan's pitchfork in the Christian tradition.

In Ceremonial Magic, a necromantic trident is fashioned of hazel wood. The old grimoires state that it should be cut at the full moon, from a tree that has never borne fruit, and with a knife whose blade has not previously been used. The shaft of the Trident is then engraved with the magic words "Tetragammaton" and "Jehova."

Charles Ploix (La Nature et les Dieux) associates the trident with the wand used in water witching. Mircea Eliade suggests that the trident was originally a representation of the teeth of sea monsters, aligning it with Poseidon's world and with the three-headed Cerberus.

Software that renders HTML pages (Web pages). It turns the HTML layout tags in the page into the appropriate commands for the operating system, which causes the formation of the text characters and images for screen and printer. Also called a "layout engine," a rendering engine is used by a Web browser to render HTML pages, by mail programs that render HTML email messages, as well as any other application that needs to render Web page content. For example, Trident is the rendering engine for Microsoft's Internet Explorer, and Gecko is the engine in Firefox. Trident and Gecko are also incorporated into other browsers and applications. Following is a sampling of browsers and rendering engines. See HTML and render.
