This article examines the interrelationship andinteractions between the notions of Son of Heavenand Son of God with respect to sacral kingship inInner and East Asia by first uncovering a previouslyunnoticed synthesis of the two in ancient InnerAsia. The author argues that the Chinese belief of“heaven” and related political and religiousconcepts may share a common origin with parallelnotions in Altaic cultures, possibly intertwinedwith Indo-European elements. Nevertheless, bystudying theophoric names, which existed in allmajor Old World civilizationsexcept early China, hedemonstrates the distinctness of Chinesecivilization, as well as the extensive pre-IslamicIranic influences in East Asia.
