Interestingly, Shankara was not immediately recognized as Hinduism's preeminent philosopher. Until the 11th century, contemporary Mandana Mishra overshadowed him in references. No Buddhist, Jain, or Hindu sources mention him for three centuries after his death. His transformation into a legendary figure occurred primarily in the 14th century when the Sringeri Matha received Vijayanagara Empire patronage. Vidyaranya, the 12th Jagadguru of Sringeri, composed elaborate hagiographies portraying Shankara as Shiva's incarnation. The Madhaviya Shankara Digvijaya formalized his legend. He became a rallying symbol for Hindu revival during Islamic rule. By the 15th century, Shankara had been elevated from brilliant philosopher to divine avatara, culture hero, and savior of Hinduism. Modern scholars distinguish the historical Shankara (8th century philosopher-monk who systematized Advaita) from the legendary Shankara (miracle-working god incarnate). Both versions, however, acknowledge his extraordinary intellectual achievement and institutional impact that shaped Indian civilization.
