The calmecac (, from calmecatl meaning "line/grouping of houses/buildings" and by extension a scholarly campus) was a school for the sons of Aztec nobility (pīpiltin ) in the Late Postclassic period of Mesoamerican history, where they would receive rigorous training in history, calendars, astronomy, religion, economy, law, ethics and warfare. The two main primary sources for information on the calmecac and telpochcalli are in Bernardino de Sahagún's Florentine Codex of the General History of the Things of New Spain (Books III, VI, and VIII) and part 3 of the Codex Mendoza.
