At the British Museum's web site, I found a photograph of an antique star tile that carries a poetic inscription around its edges. Written in an Arabic script, this is the verse (and I've taken the liberty of breaking the anonymous translator's lines):
Last night the moon came to your house,
filled with envy I thought of chasing him away.
Who is the moon to sit in the same place as you?
The words are by an unidentified Persian poet. According to the British Museum, "Love poetry is sometimes found on tiles in medieval Iranian shrines. The love it refers to is often the divine love described in Sufi mystical poetry."
