 These included Vishnu Sarma's "Panchatantra", the "Hitopadesha", "Vikram and The Vampire", and Syntipas' "Seven Wise Masters", which were collections of fables that were later influential throughout the Old World.Ben E. Perry (compiler of the "Perry Index" of Aesop's fables) has argued controversially that some of the Buddhist "Jataka tales" and some of the fables in the "Panchatantra" may have been influenced by similar Greek and Near Eastern ones.Earlier Indian epics such as Vyasa's "Mahabharata" and Valmiki's "Ramayana" also contained fables within the main story, often as side stories or back-story.
