Few examples still exist of a special type of Oriental carpet, termed "animal carpets" because their main feature are confronted animals. Dated to the 13th–16th century, they represent carpets woven during the transition period between the late Seljuq and the early Ottoman empire. Parallels were shown between the "opposed animal" and "latch-hook" motifs from woven pile rugs and the Lorestān bronzes. These are Early Iron Age bronze artifacts of various individual forms which have been recovered from Lorestān and Kermanshah areas in west-central Iran.
