From hieroglyphs to barcodes, symbols have been used throughout history. Symbols can be observed on traffic signs, warning signs that are affixed to building fronts, doors of public restrooms to show gender-specific usage, and caution signs on caustic or poisonous chemicals; even Braille, a system of writing and printing for the blind, is a symbol form. This article includes a brief discussion on the psychology of symbols, history of symbols, symbols used by alchemists and pharmacists, and the current use of symbols.
