The is a Triumphal Chariot of the World, by late 16th century Flemish engraver Phillipp Galle. As best as I can tell, the two horses represent Day and Night. The ladies at the four corners appear to symbolize the four elements of fire, air, water, and earth.
I think it would be interesting to create a Tarot in which each trump is depicted as a chariot in a triumphal procession. This German website has more information on the image above.
