Edward H. Schafer, however, maintains that An Lushan is probably the Sinicized version of a name derived from "Anxi" (安息 "Parthia(n)") and the common Sogdian name ܪܘܚܫܐܢ "Roxshan" meaning "the Bright", related to the Sogdian female name "Roxana", also borne by Alexander's Sogdian wife, Roxana. His name has also been transcribed as "Āluòshān" () or "Yàluòshān" (), and he was posthumously named Prince La of Yan () by his deputy Shi Siming.
