What is in this image? Describe it as if you were explaining it to someone from the 15th century.

This image portrays a fantastical scene, reminiscent of a great and distant realm. At first glance, one observes several grand and unique structures that do not resemble the traditional buildings and bridges you might be familiar with. In the foreground, there are two vertical, column-like constructions of great height, standing close yet not touching, accompanied by a third smaller and wide structure. These might seem to resemble the tall spires of a cathedral, but they are far simpler in design, almost stark and unadorned.Behind these central figures is a bowl-like object balanced on a pedestal, an item that could be likened to an astronomer''s tool or perhaps a ceremonial basin. To the right, a proud standard bears a design, which in your time, would be enigmatic—a symbol of an unknown noble house or a distant land.In the distance, there lie what appear to be two massive arcs, stretching over the expanse of a tranquil water body. They could be conceived as extraordinary, oversized bridges, though their form is smooth and uninterrupted, unlike the stone and wood constructions used in your age.This scene, with its curious blend of architectural wonder and tranquility, mirrors the imaginative tales told by travelers from distant lands, speaking of places that one could scarcely believe to exist. The word "BRASÍLIA" boldly adorns the scene, suggesting that this is a depiction of a land or a city of great importance, one that holds wonders far different from those known in the 15th century.
