The Historia silense, also called the Chronica silense or Historia seminense, and more properly Historia legionense, is a medieval Latin narrative history of the Iberian Peninsula from the time of the Visigoths (409–711) to the first years of the reign of Alfonso VI of León and Castile (1065–1073).
