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

The object depicted in this artwork is a wondrous flying contraption, unlike anything known in your time. Imagine a large chariot, but instead of being drawn by horses, it has two great spinning wheels affixed atop its wings, which allow it to soar through the skies like a bird. It possesses a sizeable flattened board atop it as well, somewhat akin to a millstone, but used here for navigating and stability in the air rather than grinding grain. This magical carriage also features eyes, giving it a whimsical, almost living presence. It glides high above the earth, held aloft by mechanisms unknown and marvelous, harnessing the air itself to traverse vast distances at great speed. This is no beast or natural phenomenon but a crafted marvel of human ingenuity, an echo of Daedalus''s craft but far surpassing it in both size and capability.
