On the north coast, the Moche succeeded the Chavín. The Moche flourished about 100–800 CE, and were among the best artisans of the Pre-Columbian world, producing delightful portrait vases (Moche ware), which, while realistic, are steeped in religious references, the significance of which is now lost. For the Moche, ceramics functioned as a primary way of disseminating information and cultural ideas. The Moche made ceramic vessels that depicted and re-created a plethora of objects: fruits, plants, animals, human portraits, gods, demons, as well as graphic depictions of sexual acts. The Moche are also noted for their metallurgy (such as that found in the tomb of the Lord of Sipán), as well as their architectural prowess, such as the Huaca de la Luna and the Huaca del Sol in the Moche River valley.
