The correct option is Achaemenian Empire.
Explanation
The Mauryan period, particularly under Emperor Ashoka, marked a significant transition from wood to stone in Indian architecture. The tradition of erecting monumental stone pillars during this era exhibits distinct stylistic parallels with the architectural traditions of the Achaemenian (Persian) Empire.
Similarities and Influences:
- Polished Finish: Both Mauryan and Achaemenian pillars are characterized by a lustrous, glass-like polish. In the Indian context, this is often referred to as the "Mauryan polish."
- Capital Design: The bell-shaped capital found in Mauryan pillars (often interpreted as an inverted lotus) bears a resemblance to the bell-shaped bases of Achaemenian columns found at Persepolis.
- Animal Motifs: The use of animal figures (lions, bulls) crowning the pillars is a feature common to both traditions.
- Royal Inscriptions: The practice of engraving royal edicts on stone pillars to proclaim the emperor's laws is similar to the inscriptions of Persian kings like Darius.
Structural Differences:
- Construction: Mauryan pillars were monolithic (carved from a single piece of stone, usually Chunar sandstone), whereas Achaemenian pillars were constructed from separate segments (masonry).
- Placement: Mauryan pillars were independently erected free-standing monuments. In contrast, Achaemenian pillars were generally part of larger architectural structures, serving to support the roofs of state halls.
Key Takeaway:
While Mauryan pillars display indigenous innovation in their monolithic construction, their polished finish and bell capitals reflect significant artistic influence from the Achaemenian Empire.
