Sefer HaYashar (not to be confused with an ethical text by the same name) is a midrash that covers biblical history, from creation until the period of the judges. Named after an ancient text referred to in Joshua 10:12 and II Samuel 1:17, the work is also referred to as the Toledot Adam or Divrei HaYamim HeArukh. The introduction describes how a Roman general discovered the work during the destruction of the Second Temple, but scholarship has long maintained that the work is medieval.
