Jean Pierier of Mailly, called Jean de Mailly, was a Dominican chronicler working in Metz in the mid-13th century. In his Latin chronicle of the Diocese of Metz, Chronica universalis Mettensis,[1] the fable of Pope Joan first appears in written form.[2] He is also the compiler of the Abbreviatio in gestis sanctorum, a collection of legends about the saints which is an important forerunner of the Golden Legend.
