Manuel Chrysoloras (late 14th-early 15th century) wrote from Italy, lamenting that both covered and open cisterns ("suspended through walls", "airborne rivers") and reservoirs now house gardens, implying they were out of use.

Despite falling into disrepair, the reservoir is still listed as a landmark in a late 15th-century manuscript., now under the name of "Of the Prodromos" (reference to the church of St John Prodromos/the Baptist nearby).

Gilles, visiting mid-16th century confirms that the reservoir was filled with a garden, but he misidentified it as the Cistern of Bonus.
