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

In this parchment-like sketch, you would see a mechanical carriage, unlike the horse-drawn carriages you know. This carriage looks whimsically alive, with windows appearing as eyes and a front design that mimics a smiling face. It holds the number ''5,'' likely a way to distinguish it from others of its kind, much like the flags or markings on a ship. It moves without animals, propelled by unseen forces akin to windmills turned inside-out.In the background, there are structures drawn simply but representing buildings higher than any cathedral or palace tower, with sharp angles and flat walls. To its left, a peculiar pole bears a round sign, perhaps a marker or a signal for others. The ground shows simplistic puffs of cloud, indicative not of the sky but perhaps of the air being disturbed by the passage of this wondrous vehicle. These creations belong to an age far advanced from ours, with mechanizations that harness the powers of nature in ways we can only tie to alchemy or the miraculous.
