Between 500 and 1000 AD, fired clay and carved marble objects were created in the lower Ulúa river valley in what archaeologists today call Ulúa style. Ulúa-style figurines and painted pots were produced in multiple workshops dispersed throughout the region. Ulúa marble vases were produced in smaller numbers, most likely in workshops in a single town. In all three media, Ulúa style emphasised adherence to conventional patterns of images, resulting in the production of multiple objects with the same images.
