Reviewing aerial photographs of a Romano-British temple in what is now Berkshire (formerly Oxfordshire), archaeologists noticed a large, dark oval mark on the ground near the temple site.
Wisely, they consulted with the local man who actually farmed the land, and so knew it best.

Excavations later revealed the reason for the Anglo-Saxon name. Beneath the field lay the remains of a Roman amphitheater.
A review of surviving medieval documents never mentioned the name Trendles. Experts in British place-names had never heard of it.
