6. STYLE OF ART AND ARCHITECTURE
The Sultanate introduced two new architectural ideas, the dome
and the pointed arch. The dome was an important decorative
structure in Islamic buildings, and soon was implemented in
other structures as well. The pointed or true arch that was
introduced during this period, was completely different from the
type of arches that were being constructed within the country
earlier. The earlier Indian style of creating arches was to first put
up two pillars. The pillars would then be cut at intervals
accommodate 'plug in' projections. There would be a sequence
of squares that would gradually decrease in size creating an arch.
The new artisans introduced the true arch. This was achieved by
making the middle stone a key stone and to have the other
stones distribute the load of on the two pillars.
