A number of similar capitals are known, although a close inspection shows that almost all of them differ slightly one from another. The present capital is very similar indeed to a number of examples which can be dated to the reign of Al-Hakam II, one of the best of which, bearing a signature and date, is in the al-Sabah Collection, Kuwait (Jerrilynn D. Dodds (ed.), Al Andalus, New York, 1992, no.39, p.247). Even more similar in terms of decoration and size is one that was excavated at Medinat al-Zahra and is dated to the second half of the tenth century (El Esplendor de los Omeyas cordobeses, exhibition catalogue, Granada, 2001, pp.120-1).
One side of this capital was clearly never designed to be finished. not only is there no decoration, but the volutes do not extend as far as those on the other sides so could never have been carved fully. It was probably intended for use on an engaged column, leaving the simpler side next to the wall.
A very well preserved capital of similar layout and decoration was sold in these Rooms, 11 October 2005, lot 21.
