The original tetralogies were sets of four plays (three tragedies and a comedy) performed serially on the Athenian stages of ancient Greece. These sets of plays were similar to the "trilogy," a group of three serial Greek tragedies. The word "tetralogy" is from the Greek combining form "tetra-," meaning "four," joined with the combining form "-logia," which in turn comes from "logos," meaning "word." Other "tetra-" words include "tetrahedron" (a solid shape formed by four flat faces) and "tetrapod" (a vertebrate with two pairs of limbs).
