"Socially and culturally, Tekumel is as complex – and as alien to modern thinking – as Byzantium, ancient Egypt, Tenochtitlan, or the India of the Mughals. [...] The discerning reader will indeed perceive elements taken from [...] Egypt, the Aztecs and Mayans, the Hellenic Age, Mughal India, and mediaeval Europe."
