The Edictum Rothari (also Edictus Rothari or Edictum Rotharis) was the first written compilation of Lombard law, codified and promulgated 22 November 643 by King Rothari. The custom (cawarfidae) of the Lombards, according to Paul the Deacon, the Lombard historian, had been held in memory before this. Now it was promulgated in Latin, a very vulgar and coarse Latin, by the king with the advice and consent of his council and his army.
