Not sure about D&D but I seem to recall there being symbols in the Baldur's Gate game assoc with the schools of magic. This is what I can recall:Abjuration: a shieldConjuration: a beastDivination: a crystal ballEnchantment: ?Illusion: a faded outline of an imageInvocation: a finger shooting a magic missileNecromancy: a skullTransmutation: ?

I have found on google two images that seens to be the representations of the schools.This image seens to be AD&D or older, or even unofficial material, the names of the schools are in portuguese. And from top, clockwise goes:Illusion, Enchantment, Conjuration, Abjuration, Necromancy, Evocation, Divination and Transmutation.
