Sheikh Lotfollah Mosque (Persian: مسجد شیخ لطف الله)[2] is one of the masterpieces of Iranian architecture that was built during the Safavid Empire, standing on the eastern side of Naqsh-i Jahan Square, Esfahan, Iran.

Also, as in the Masjed-e Shah, the lower façade of the mosque and the gateway are constructed of marble, while the haft-rangi tiles (Persian: هفت‌رنگی, lit, "seven-coloured", "polychrome mosaics") decorate the upper parts of the structure.

[7] The monument's architect was Mohammad-Reza Isfahani, who solved the problem of the difference between the direction of qibla and gateway of the building by devising an L-shaped connecting vestibule between the entrance and the enclosure.

[9] This feature, called pāshnah (پاشنه) in Persian architecture,[10] has caused the dome to stand not exactly behind the entrance iwan (see picture).

[12] However, in contrast to the simple structure of this mosque, the decoration of both interior and exterior is exceedingly complex,[13] and in its construction the finest materials were used and the most talented craftsmen employed.

[15] Barbara Brend described as follows: "the turquoise cable moulding of an arch is seen below the dome, in which concentric rings of thirty-two lozenges diminish in size as they approach a centre which gives an impression of luminosity.

The design, which suggests both movement and stillness, is a powerful though not an explicit vehicle of religious symbolism, speaking of the harmony of the universe.

Within the dome, ranks of units of tilework of ogee-mandorla form are set in a lattice of plain brick and diminish in size until they meet a central sunbrust patterned with a tracery of arabesque".

[20] It has been suggested that concepts of the mystic philosopher Suhrawardi about the unity of existence was possibly related to this pattern at the interior side of the dome.

[23] The running inscription in white tile on blue ground on the exterior drum of the dome, visible to the public, consists of three surah (chapters) from the Quran; al- Shams (91, The Sun), al-Insan (76, Man) and al-Kauthar (108, Abundance).

[24] Turning right at the entrance to the domed prayer chamber, one first encounters the full text of Surah 98, al- Bayyina, the Clear Proof.

The message of this chapter is that clear evidence of the true scripture was not available to the People of the Book (i.e. Christians or Jews) until God sent his messenger Muhammad.
