Back in August, I was lucky enough to be taken on a guided tour of Iruña-Veleia, a Roman oppida in El Pais Vasco, northern Spain. I posted some pictures and a very brief blurb about the site in this entry. One of the things I mentioned (although have since edited) was the claim that artefacts from the site included the oldest known depiction of the crucifixion, and the the oldest-known inscriptions in Basque. This was information I lifted uncritically from news stories about the site and from the Spanish and English Wikipedia entries , and which this week was revealed to be false. Indeed it appears that an archaeological hoax has been perpetrated.
Here is a link to the story in The Guardian.
I take this as a lesson, and shall certainly be more careful about the evidential traceability of claims I refer to on this blog.
