The aluminum cistern collects roof watershed from the 81 Vine Street building. Water is directed from the roof via downspout then through the extended index finger of an outstretched hand and into the 10' x 6' dia. tank "cuff" before eventually making its way down Vine Street to the Cistern Steps. The gesture of the outreaching finger suggests that of the Creation of Adam by Michelangelo from the Sistine Chapel in Rome.
