The graphic elements of Mesoamerican codex writing appear as figural representations, icons, and symbols that signify thought, ideas, and imagery rather than visible speech. Although ancient Mexicans designated some symbols to voice specific words, their larger graphic system did not correspond directly with spoken language. Because the symbols did not replicate any single linguistic system, speakers of various languages could translate the pictographs into their own respective tongues. Readers evaluated a combination of naturalistic images, pictorial conventions, and abstract symbols recorded within an organized structure. By knowing the basic conventions and the meanings of the symbols and recognizing their general arrangement, readers interpreted the pictographic messages. Precise reading orders are not always set, however; thus, different readings and interpretations remain possible.
