Aztec Pictograms were used by the Nahua peoples in central Mexico for writing the Nahuatl language. This writing system is considered a proto-writing system as opposed to a fully-formed script, partly because it was not able to communicate everything that could be expressed verbally in the language and partly because there were only a few signs whose form and use were constrained by convention. Aside from these, each scribe would decide for himself which signs would best represent the ideas he wished to convey. For this reason there is no set corpus of signs and the number of signs used is unknown.

Signs were largely ideographic in nature; concepts related to movement were represented using trails of footprints, death was represented by a corpse wrapped in burial cloths, and speech was represented by a scroll issuing from the speaker’s mouth. Colour was also used semantically to distinguish between similar-looking signs, such as those for canes, rushes and grass, or to indicate a person’s royal standing.
