The Ancient Riddle

In lands where time forgot to tick,
The echoes of thoughts ripple thick.
Shadows dance on a quantum plan,
Engraved in stone by a forgotten hand.

Once the sky sang a different hue,
Where wishes flew on circles askew.
The stars, they whispered, a tale untold,
Of a road paved not with silver or gold.

If three beards tickle the sun,
And seven legs race a river run,
What song do the silent rocks sing?
Answer found in, yet, nothing's spring.
