This paper brings in new and not-well-known archaeological evidence to the debate over the Samarra Horizon, and reviews some preconceptions of the green splashed ware and blue painted ware through Chinese ceramic imports found in several sites in the Middle East from the eighth to tenth centuries CE. There has been mutual influence between Islamic and Chinese ceramics in the early Abbasid period, and there may be more than one explanation for their visual similarities.
