The Sarnath Lion Capital was erected to commemorate which significant historical event?

The correct option is The first sermon by the Buddha.

Explanation

The Sarnath Lion Capital is a quintessential example of Mauryan court art, specifically the monolithic pillars erected by Emperor Ashoka. These pillars were often established at sites associated with the life of the Buddha to propagate Dhamma.

Option Analysis:

• The first sermon by the Buddha is Correct: The Sarnath pillar was erected by Emperor Ashoka to commemorate the Dhammachakkappavattana, or the "Turning of the Wheel of Law." This event marks the first sermon delivered by Gautama Buddha to his five disciples at the Deer Park in Sarnath.
• The birth of Ashoka is Incorrect: The pillar is a Buddhist monument intended to mark a sacred site related to the Buddha's life, not the birth or personal milestones of Emperor Ashoka.
• The victory in the Kalinga War is Incorrect: Although the Kalinga War was the pivotal event that led Ashoka to embrace Buddhism, the Sarnath Capital specifically marks the location and event of the Buddha's first teaching, rather than the war itself.
• The foundation of the Mauryan Empire is Incorrect: The Mauryan Empire was founded by Chandragupta Maurya. The Sarnath Capital was commissioned much later during the reign of his grandson, Ashoka (c. 250 BCE).

Key Takeaway: The Sarnath Lion Capital symbolizes the universal proclamation of the Dhamma and specifically marks the site of the First Sermon (Dhammachakkappavattana) given by the Buddha.
