Isocolon

Isocolon is a figure of speech in which a sentence is composed of two or more parts (cola) perfectly equivalent in structure, length and rhythm: it is called bicolon, tricolon, or tetracolon depending on whether they are two, three, or four. A well-known example of tricolon is Julius Caesar's "Veni, vidi, vici" ("I came; I saw; I conquered).
