Question

Why were the shields of Arthur’s knights hanging on a tree Turquine’s land?

Answer 1

 Shields of Arthur's knight were hanging on a tree in Turquine's land because  on the tree "hangeth a basin of copper and latten, and if thou strike upon that basin thou shalt hear tidings.”

Answer 2

Answer:

• Turquine requested all guests leave their weapons and shields there before entering his home.

Explanation:

Turquine had his very own accumulation point for vanquished adversaries on the slope named for him. Close to this slope was a wellspring going through a silver cylinder onto a marble piece and thereupon into a heavy vessel.  

The wellspring was dominated by three pines on which hung the shields, protective caps, and spears of the knights Terican had won. At the point when Sir Ector de Maris touched base, there were sixty shields, including twenty-four having a place with knights of Arthur. Likewise close or almost certain on the slope was where Terican kept his detainees.
