The rock-sculpture at Behistun was also his work.

In attention to the creation of permanent historical records he excelled all the Persian kings, both before him and after him.

The only really historical inscription at Persepolis is one set up by Darius.

He was the only Persian king, except perhaps one, who placed an inscription upon his tomb.
