1191 (587 A.H.) the inscription of the inner Eastern gateway of the Quwwat ul Islam Mosque (meaning 'Might of Islam') in Delhi was written by pure Naskh. The language of this inscription is Persian and it is interesting to know that Persian appears to be used for epigraphic purposes in India much earlier than Iran.

The styles of calligraphy as seen in the inscriptions of the above Sultans reached their culmination in the Khalji period (1288-1321 C.E.). Then the latter half of the Tughlaq period (1321-1414 C.E.) saw the appearance of some new styles. The reign of the Sayyid dynasty (1414-1450 C.E.) was very brief and there seems to have been no new development in the field of calligraphy during that period. But the calligraphers of the Lodi period (1451-1526 C.E.) appear to have shown some new styles of calligraphy.
