It also mentions that the fountain's construction was supervised by the sultan's vizier, Abu Zakariya Yahya ibn Ziyan al-Wattasi (who founded the subsequent Wattasid dynasty). Lastly, it indicates that construction was finished on Jumada I, 840 AH (November 11, 1436 CE). Another line added just above the original text states that the fountain was restored in 1090 AH (1679 CE).[67] The fountain has thus been much restored, and Alfred Bel believed that it was probably once covered in carved stucco decoration which was then lost over time.[67] The inscription and the small marble panel ornaments are from the original Marinid construction, while the wooden canopy above dates from the 17th century restoration.[67] Today, some tiles along the top of the water basin visibly indicate, in both French and Arabic, a modern restoration in 1986.
