1. To the left we can recognize a sign which I guess means 'light'.
2. To the right we can recognize a sign which I guess means 'spear of power' or something similar, an instrument for the ruling power.
3. In the middle we can see an raised arm with an open hand. This could mean the act of 'taking' (as in taking command).
4. All together these three signs probably is telling something like this: 'the light is taking over' (from the dark), an appropriate description of spring equinox.
