The lion and the bull, and the astronomy in Persepolis

The lion and bull combat is a recurrent theme among Persepolis sculptures.

Its meaning is considered from certain experts as the seasonal change at the time of vernal equinox: the lion, symbol of the summer sun, defeats the bull, winter’s rain. Other experts note that at Persepolis, come dusk on the equinox, the constellation Leo (the lion) is at its zenith and Taurus (the bull) is setting.
