 Poseidon ( Linear B : Po @-@ se @-@ da @-@ o ) seems to have occupied a place of privilege . He was a chthonic deity , connected with earthquakes ( E @-@ ne @-@ si @-@ da @-@ o @-@ ne : Earth @-@ shaker ) , but it seems that he also represented the river spirit of the underworld . Paean ( Pa @-@ ja @-@ wo ) is probably the precursor of the Greek physician of the gods in Homer 's Iliad . He was the personification of the magic @-@ song which was supposed to " heal " the patient . A number of divinites have been read in the Mycenaean scripts only by their epithets used during later antiquity . For example , Qo @-@ wi @-@ ja ( " cow @-@ eyed " ) is a standard Homeric ephithet of Hera . Ares appeared under the name Enyalios ( assuming that Enyalios is not a separate god ) . Additional divinities that can be also found in later periods include Hephaestus , Erinya , Artemis ( a @-@ te @-@ mi @-@ to and a @-@ ti @-@ mi @-@ te ) and Dionysos ( Di @-@ wo @-@ nu @-@ so ) . Zeus also appears in the Mycenaean pantheon , but he was certainly not the chief deity .
