The Christian cross, seen as a representation of the instrument of the crucifixion of Jesus Christ, is the best-known religious symbol of Christianity. It is related to the crucifix (a cross that includes a usually three-dimensional representation of Jesus' body) and to the more general family of cross symbols.

The cross-shaped sign, represented in its simplest form by a crossing of two lines at right angles, greatly antedates, in both East and West, the introduction of Christianity. It goes back to a very remote period of human civilization. It is supposed to have been used not just for its ornamental value, but also with religious significance.

Some have sought to attach to the widespread use of this sign, in particular in its swastika form, a real ethnographic importance. It may have represented the apparatus used in kindling fire, and thus as the symbol of sacred fire or as a symbol of the sun, denoting its daily rotation. It has also been interpreted as the mystic representation of lightning or of the god of the tempest, and even the emblem of the Aryan pantheon and the primitive Aryan civilization.

David Silverman (born on March 15, 1957 in New York City, New York) is an American animator best known for directing numerous episodes of the animated TV series The Simpsons, as well as The Simpsons Movie. Silverman was involved with the series from the very beginning, where he animated all of the original short Simpsons cartoons that aired on The Tracey Ullman Show and went on to serve as director of animation for several years.

Started his education at the University of Maryland, College Park for two years, focusing on art. Then he attended UCLA and majored in animation.

Early in his career with The Simpsons, he was a subject on the December 26, 1990 episode (#83) of To Tell the Truth.

Silverman is largely credited with creating most of the "rules" for drawing The Simpsons. He is frequently called upon to animate difficult or especially important scenes, becoming to go-to in Season 2 when he animated the first of Homer's many "rants, freak-outs, and heart attacks". He appeared during the end credits of the Simpsons episode "Goo Goo Gai Pan" giving a quick method of drawing Bart, and is a frequent participant on the Simpsons DVD audio commentaries. A cartoon rendering of him can be seen in "The Itchy & Scratchy & Poochie Show", where he is the animator who draws Poochie (along with renderings of other Simpsons staffers). He was once credited as Pound Foolish as the director of the episode "The Simpsons 138th Episode Spectacular".
