M.L. West (1937-2015), The East Face of Helicon: West Asiatic Elements in Greek Poetry and Myth
(1997; rpt. Oxford: Clarendon Press, 2003), p. 54:
An ancient god is a complex entity, a compound made up from some or all of the following: a name, or rather, a cluster of names and titles; a poetic persona; a mythology; a doxology; an iconography; a constituency, defined by geographical or social factors; a set of prompts, I mean situations and occasions when the god is brought to mind; a 'dromenology', that is, a repertory of cult activities.
