《资治通鉴·唐纪·唐纪二十》
张嗣明诬告内史张光辅，说 征讨豫州时，他私下议论王者受命的征验、天象变化，在朝廷和叛逆者间脚踩两只船。 
嗣明诬内史张光辅，云 征豫州日，私论图谶、天文，阴怀两端。 
Zhang Siming falsely accused Interior Minister Zhang Guangfu, saying that when going to battle in Yuzhou, he had privately discussed omens of the rightful ruler and changes in the heavenly bodies, and had equivocated between the court and the rebels.
