CLASSICAL AND ARCHAEOLOGICAL DICTIONARY BY P. AUSTIN NUTTALL, LL.D.
PANDEIA (Pandia) was a daughter of the sky-god Zeus and the moon-goddess Selene. She was perhaps the goddess of the full moon (panselênê in Greek), the earth-nourishing dew (hersê) or youth.
Several other writers mention a daughters of Zeus and Selene named Ersa (Dew) and Nemeia. It is not clear if these were three distinct goddesses or just alternate names for one. She might also be connected with the Menai (Months), fifty daughters of Endymion and Selene.
