I think we might be getting closer...
Ishtar's famous title was "the Queen of Heaven". Her cult survived into Chjristian times, buit she also morphed into other goddesses like
Astarte and Aphrodite ("Ourania", the "Heavenly One").
According to
Wikipedia: "Worship of
Venus deities possibly connected to Inanna/Ishtar was known in Pre-Islamic
Arabia right up until the
Islamic period. Isaac of
Antioch (d. 406 AD) says that the Arabs worshipped 'the
Star' (kawkabta), also known as Al-Uzza, which many identify with
Venus. Isaac also mentions an Arabian deity named Baltis, which according to Jan Retsö most likely was another designation for Ishtar. In pre-Islamic Arabian inscriptions themselves, it appears that the deity known as Allat was also a Venusian deity."
So at the moment I'm guessing that this little object was connected with a pre-Islamic Arabian sky-goddess cult. But it would be
good to know whether anyone has ever seen anything similar?
