[Jharkhand P.C.S. (Pre) 2016]

Detailed Solution & Historical Context

Concept

A 'True Arch' is constructed using wedge-shaped blocks (voussoirs) that transfer the load sideways, a technique that was not common in India before the Sultanate period.

Authentic Source Evidence

The Tomb of Ghiyas-ud-din Balban (built c. 1287) in the Mehrauli Archaeological Park is recognized as the first extant structure in India where a true scientific arch was successfully built. Earlier attempts at arches (like in Iltutmish's tomb) were 'corbelled' (pseudo-arches made by overlapping flat stones).

Analytical Breakdown

Logic 1: Balban's tomb represents the moment when local Indian masons mastered the Persian technique of the scientific arch.

Logic 2: While the Alai Darwaza (1311) features much more refined true arches, Balban's tomb is the earlier historical prototype.

Conceptual Deep Dive & Logic

"What is the difference between a corbelled arch and a true arch?"

A corbelled arch is made by stepping stones inward until they meet, while a true arch uses wedge-shaped stones to distribute the load.

Examiner's Mindset & Pro-Tip

"The mastered true arch allowed Sultanate architects to build larger, higher structures without the need for massive internal pillars."
