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

This image shows a lively and bustling city drawn in a manner quite unlike anything from our time. At the top, the name "Warszawa" is boldly proclaimed, likely the name of this grand settlement. At the forefront, there is a fantastical creature, perhaps a type of ethereal maiden floating in the sky, holding onto what appears to be a long ribbon or streamer. She is atop a creature that is half fish, half cloud, blending elements of the sea and the air in a wondrous fashion.Below her, there lies a grand cityscape. Towering structures, some of which reach into the heavens, dominate the skyline. These buildings are unlike any castle or cathedral; they have sharp points and flat sides and are closely set together. In the foreground, smaller, detailed dwellings reminiscent of your own era''s sturdy stone houses are visible, but with more regularized and uniform appearances. In front of these buildings, there is a surreal pathway for a mystical carriage which does not rely on horse or oxen. This carriage is long and segmented, moving seemingly of its own volition along fixed tracks laid upon the ground. It bends and turns gracefully along these tracks, headed toward a large arched bridge crossing over a meandering river that flows gently through the city.This depiction merges the familiar with the magical and would likely seem a fantastical scenario of future times to someone from the 15th century. The combination of familiar landscapes, such as rivers and bridges, with these strange, towering structures and the mystic carriage, would be quite out of the ordinary and ignite the imagination.
