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

In the image, there is a scene with a cheerful craftsman, a large metal carriage but without horses, and several circular objects that may remind one of barrels. The craftsman, who wears a protective garment and a helmet reminiscent of a smithy''s headgear, wields a tool in one hand and gestures joyfully with the other, as though in the middle of a hearty tale. The large metal carriage, a marvel of our modern times, is known as an automobile – a self-moving wagon that needs no horses and runs on the spirit of fire and air, encased within its bowels. This automobile has its front lifted open, revealing its inner workings, much like the opening of a chest revealing treasure. On the ground before the carriage lie what appear to be four barrels, but these are, in fact, the wheels — round pieces that hold the carriage aloft and allow it to move. These are off the vehicle, suggesting that the craftsman is in the process of repairing or replacing them. Nearby, a small box with a skull marks, alludes to the presence of some poison, perhaps a cleaning solution or a substance to aid in the repair. In the background, a simple structure with a rectangular opening (like a door) stands beside some scattered tools, and the scene is completed by a grassy patch and a hint of a sky with clouds, hinting that this activity is happening outside, possibly near the craftsman''s workshop.
