Epimetheus

In Greek mythology, Epimetheus (/ɛpɪˈmiːθiəs/ ^ⓘ; Ancient Greek: Ἐπιμηθεύς, lit. 'afterthought') is the brother of Prometheus, with the complementary pair serving as archetypal representations of mankind. Both are sons of the Titan Iapetus; while Prometheus ("forethought, or foresight") is portrayed as ingeniously clever, Epimetheus ("afterthought, or hindsight") is considered inept and foolish. In some accounts of the myth, Epimetheus unleashes the unforeseen troubles in Pandora's box.
