"The Ica stones were a hoax and officially a branch of the tourist industry. It was over… or was it? When dealing with controversies of this sort, nothing is ever simple. Believers in the antiquity of the stones claimed that the farmer admitted to the hoax for a very simple reason: if the stones were genuine, he had been selling government possessions. Peruvian law dictates that archæological discoveries should be turned over to the government and he faced prison if found guilty. By admitting it was a simple hoax, the farmer was let off the hook… and was able to provide his family with an income. When von Däniken visited the farmer in 1973, Uschuya confirmed to him that he had faked the stones; but later on, in an interview with the German journalist Andreas Fischer, Uschuya claimed the opposite. They were genuine, he insisted, and he admitted to a hoax to avoid imprisonment."
