Eight other examples of these have been published. Four were on the London art market (Fehervari and Safadi nos.54a-d) while four others are in the Linden Museum, Stuttgart (catalogue p.29, fig.25). A further unpublished group is in the al-Sabah collection, Kuwait. Each contains one of the hundred names of God. It seems probable that the group formed an upper decorative feature on a Safavid shrine, a theory supported by the small lugs at the base of each.
