Piranesi was an 18th-century Italian architect and printmaker who documented Roman ruins. This etching shows the remains of Aqua Claudia, an ancient aqueduct bringing water from mountain springs to Rome. The structure represents infrastructure that draws water from a distant source and distributes it to the city, relating to hexagram 48's image of the well. This is Jǐng (井), The Well, the hexagram representing the unchanging source that serves the changing community. The character depicts the grid pattern of fields surrounding a central well—eight families drawing from one shared source. The trigram structure places Water (Kǎn) above Wind (Xùn): water drawn upward by wood, the rope and bucket penetrating the depths to bring sustenance to the surface. Piranesi's aqueduct extends this principle monumentally—the ancient well become public infrastructure, mountain springs channeled through engineering to supply urban populations. The Judgment text states: "The Well. The town may be changed, but the well cannot be changed. It neither decreases nor increases. They come and go and draw from the well. If one gets down almost to the water and the rope does not go all the way, or the jug breaks, it brings misfortune." The text emphasizes the well's constancy—dynasties rise and fall, populations migrate, but the water source remains. Piranesi's aqueduct embodies this principle: Republican Rome becomes Imperial Rome becomes Papal Rome, yet the Aqua Claudia continues carrying water from the same Anio springs. The text also warns that the well requires proper maintenance—broken jugs and short ropes bring misfortune. Piranesi documents precisely this concern: the aqueduct endures but requires care, its weathered stones testimony to both Roman engineering and centuries of upkeep. The Image Text observes: "Water over wood: the image of The Well. Thus the superior person encourages the people at their work, and exhorts them to help one another." Water rests above wood in the hexagram structure, but the practical image is the wooden bucket drawing water upward—the tool that makes the well functional. Piranesi's aqueduct serves the same function on civic scale, the infrastructure that enables city life. In the I-Ching sequence, Jǐng follows Kùn (oppression): after exhaustion comes the reminder of the reliable source, the well that neither increases in abundance nor decreases in drought, requiring only maintenance and proper use. The aqueduct's repetitive arches create rhythm across the landscape, each section like another family drawing from the shared source, the ancient infrastructure still nourishing Rome fifteen centuries after the engineers who planned it returned to earth.
