The part cross tile on the right is dated panjum-e ramadan sana thalath wa sittin wa sittami'a hijriyya nabawiyya (Fifth of Ramadan, the year six hundred and sixty three of the Prophet's migration). The other inscriptions are all from the Qur'an as follows, beginning with the dated tile:
sura xcvii, al-qadr, v.1-mid v.2.
sura i, al-fatiha, vv.1-5 and sura cxiv al-nas, v.4.
sura i, al-fatiha, vv.1-mid.v.6.
sura i, al-fatiha, vv.1-mid.v.7.
The decorative style of these tiles is very similar to that of the larger star and cross tiles from the Imamzadah Yahya, Veramin, which date from two years earlier (Watson, Oliver: Persian Lustre Ware, London, 1985, p.191). Further very similar and similarly dated examples to these are in the Metropolitan Museum, New York (Grube, Ernst: "Some Lustre Painted Tiles from Kashan", Oriental Art, vol.VIII, 1962, fig.3).
