In 2007 journalist-publisher Frank Schirrmacher wrote an article for the Frankfurt Book Fair suggesting that the Academy's preparation of a historically critical Quran edition had been motivated by Pope Benedict XVI's ill-received Regensburg lecture of 2006 and predicting that the Corpus Coranicum would spark similar outrage among Muslims, comparing it to the punishment of Prometheus for bringing fire to mankind. He was enthusiastic that the fruits of their research might even "overthrow rulers and topple kingdoms". Marx promptly called the Al-Jazeera television network to deny any attempt to attack Islamic tenets.
