The Wicker Man?

If there is one bit of data that many people know about the Druids simply because of popular culture, it is that legend has it that they would burn enormous human statues as living sacrifices to satisfy higher forces, as depicted in the 1973 and 2006 horror movies both titled The Wicker Man. This knowledge was not particularly well recognized before 1973. There are two strong pieces of literary testimony, but there is no known archaeological evidence.

Caesar actually claimed that it was a practice in Gaul, despite the fact that the original film's Summer isle, off the coast of the Britain, setting. He further mentioned that convicts with the gods' blessing would typically be offered as sacrifices. Strabo, a Greek geographer and historian who lived during Caesar's time and is most remembered for penning the most in-depth biography of Augustus Caesar at the time, served as the other witness.

He did not agree with Caesar's assertion that criminals were preferred over other human sacrifices, and his allegation was different from Caesar's in that it claimed that animals would also be included in the sacrificial statues. It makes sense why Roman emperors would want that ritual outlawed, accurate or propaganda.
