Thirty Years of Toil to Compose the Shahnameh
To complete this grand epic masterwork Ferdowsi spent nearly thirty long years, and by tradition all but exhausted his fortune in devoting himself to the writing; in his later years he presented the work to Sultan Mahmud of the Ghaznavid dynasty then ruling Persia, hoping for a rich reward to supplement his old age, but the sultan’s reward fell far below his expectation (the reason variously recorded in the sources), and this affair of grievance between sovereign and subject thereafter became a widely told case in the history of Persian literature.
