After a few centuries, the first settlement was abandoned. After the PPNA settlement phase, there was a settlement hiatus of several centuries, then the PPNB settlement was founded on the eroded surface of the tell. This second settlement, established in 6800 BCE, perhaps represents the work of an invading people who absorbed the original inhabitants into their dominant culture. Artifacts dating from this period include ten plastered human skulls, painted so as to reconstitute the individuals' features. These represent either teraphim or the first example of portraiture in art history, and it is thought that they were kept in people's homes while the bodies were buried.
