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

This image depicts a whimsical scenario where a small, flying creature, which you might think of as a witch due to its hat and broom-like apparati, is operating an advanced mechanical contraption that resembles a large wheeled carriage without horses. This mechanical carriage has many doors and a rugged design, indicating it may be used for arduous tasks. It houses an odd-looking, cylindrical instrument extending from its top, which seems as though it could be a fantastical cannon or perhaps a tool for magical interventions.Moreover, this carriage not only rolls on land but appears to have components resembling paddles and blades atop it, suggesting it might also travel through air or water, harnessing the wind like a ship at sea. It pours forth a plume of smoke at the tail end, akin to fire-breathing dragons of lore, hinting at its powered nature. In the world of the 15th century, such an illustration might be seen as a product of a vivid imagination, combining elements of folklore with fantastical mechanical advancements, possibly a tale of a traveling sorcerer with a chariot that surpasses the speed and capabilities of any steed or ship.
