    Abstract: In general, one of the traditional Iranian arts is tile work. That occurs as one of the turning points in
the Qajar era and at the time of Fath Ali Shah Qajar. Seyyed Mosque of Isfahan has been an important religious
center at the time that different functions happened at the mosque. Including the use of new techniques and
the most important the existence of red color that was known as devil. And we try to examine the reason for this
change compared to the previous periods and especially in Safavid era. Before the Qajar, the existence of red
devil, additional three dimensional techniques and third dimension or the same (relief) were Islamic absolutely
prohibited and forbidden in religious places we can consider the cause of this change can generally Sayyed
Muhammad Baqirshafti because he was a religious clergy man that due to political and financial reasons, he
was the top at that time. He could be the main sponsor of genesis of the techniques described in the tiles of the
Qajar period and in general, the founder of the Islamic religious buildings after the time of Fath Ali Shah Qajar.
In general in Islamic religious buildings red tiling was common and can be seen in many mosques in Tehran and
in that time onwards other parts of Iran has been built to date, even is effective in the art of the mosques
building and still can be found in many religious and non-religious buildings.
