Seema's grandmother was telling her a story about Tenali Ramakrishna and Emperor Sri Krishna Deva Raya. Though she enjoyed the story, she wondered if the characters in the story were real or an interesting folktale. When she checked on the internet she found out that Tenali Ramakrishna was one of the 'Ashtadiggajas', of the emperor's court during his reign (1509 CE - 1529 CE).
What is the above story an example of?
