Ancient Greek and Roman political ideals were expressed in many different forms. In both cultures, leading wealthy citizens would fund monumental buildings and endow institutions which glorified their home towns and often expressed idealized elements of political ideology.
Roman military ideals were expressed in the triumphal arches built after major imperial military victories and in the celebrations known as "triumphs" awarded to them. Other forms of monumental architecture often expressed political ideals as well, e.g. the Periclean building program reflecting the Athenian imperial ideology that emerged after the victories over Persia.
Law codes expressed and embodied ancient political ideals as did a form of oratory known as panegyric that praised the acts of political leaders and held up, as it were, a mirror of ideal behaviour against which the person being praised could be measured.
