What are the five spots of paints on the exterior of the house from waters of Babylon?

In "The Waters of Babylon" by Stephen Vincent Benét, the five spots of paint on the exterior of the house symbolize the remnants of a once-great civilization's technology and culture. They serve as a reminder of the beauty and complexity of the past, contrasting sharply with the desolation of the present. These spots evoke curiOSity and a sense of loss, prompting the protagonist, John, to reflect on the knowledge and wisdom that have been lost over time. Ultimately, they highlight themes of memory, decay, and the cyclical nature of civilization.
