This research focuses on the paintings preserved on an unusual element: a raft of water for irrigation in Bédar. Along with an Arabic text that dates the painting, one can see two four-legged animals perhaps representing a hunting scene and an ornamental top. It also preserves other highly degraded graphic signs that it has not been possible to fully decipher. As until now its chronology has not been determined, in this study, I have followed the usual method in Arabic epigraphy: (...) to draw the visible strokes and then to restore the missing or very obliterated parts of the painting. We can say that the raft and the elements that compose it were built in that rural area under Caliph al-Ḥakam II rule in the year 355/966. As a result of this study, the value of this outstanding document of Andalusian popular culture is highlighted: a pool of similar size to those that have been found in other sites of the Caliphate period. It is urgent to proceed to a professional excavation of the monument. (shrink)
