Does the superimposed temple sequence at Eridu record unbroken cult, or repeated returns to a remembered place?

The stack of temples is real and is cited everywhere as evidence of continuity, but continuity is an inference from the stack rather than something the stack demonstrates. The excavation belongs to the 1940s, its final report appeared decades later, and no radiocarbon series was run through the sequence. Whether the deposits between one temple and the next represent a few years or several centuries of abandonment is not recorded, and no one has argued the question either way for want of data.
