Aeneas worst nightmare

Sleeping Muse

The best starting point is Aren M. Wilson-Wright’s Athtart. The Transmission and Transformation of a Goddess in the Late Bronze Age (though note minor criticism courtesy of Timothy D. Leonard in Ištar in Ḫatti: The Disambiguation of Šavoška and Associated Deities in Hittite Scribal Practice). Sadly, warnings from Jo Ann Hackett’s piece published all the way back in 1989 remain relevant, as Wilson-Wright aptly demonstrates. Other than that, in no particular order:
