Historians from [[Polybius]] to [[Giambattista Vico]] and [[Karl Marx]] have entertained the notion that history moves in definite cycles. Polybius referred to political cycles, Vico believed in a three cycle-pattern based on divine intervention, and Marx believed in an economic viewpoint for history. [[A. T. Fomenko|Fomenko]]'s [[new chronology]] claim that this is due to historical records which describe same events being misdated in different time periods.
