Excerpts from the Archivo Historico Nacional in Spain in the Aragonese language correspond to a sentence of the second half of the 13th century (between 1260 and 1265). We can see among other things: the origin of the term "pieça", (piece, part), which currently holds in Llumes village to designate the farms, but is lost in the rest of Aragon; the references to localities are under its current names except for Calatayud which appears as "Calataiub". The village now called Llumes is named "Flumes" from Flumen, or "river" in Latin. The municipalities correspond with the current ones, the limit between Monterde and Llumes is still the road from Cubel to the Monastery, which is the current limit of the Parish of San Miguel.
