 Demeter , Philitas ' most famous work , consisted of elegiac couplets , or couplets in the elegiac meter . Its few surviving fragments suggest that it narrated the grain goddess Demeter 's hunt for her daughter Persephone . The fragments describe Demeter 's arrival on Cos and warm welcome by its royal family of Meropids , or humans twice normal size , thus presenting the founding myth of a local cult of Demeter on Cos .

 In the Bibliotheca , the Arcadian genealogies are immediately followed by the Atlantids , and this progression is known to mirror the structure of the Catalogue because other fragments of the papyrus roll that transmits the Telephus myth cover families of Atlas ' daughters : Taygete , Electra , Alcyone , Sterope , Celaeno , Maia and Merope . Maia bore Hermes to Zeus on Mount Cyllene . Taygete also slept with Zeus , becoming the mother of Lacedaemon , through whom much of the Spartan line was traced , including Tyndareos , the father of Helen , and Penelope , the wife of Odysseus . To Zeus yet again Electra bore Dardanus , the progenitor of the Trojan line , and Eetion , who was killed for sleeping with Demeter . Dardanus ' sons were Erichthonius and Ilus . Hyrieus and Hyperes were Poseidon 's children by Alcyone . Her section included the Ehoie of Hyrieus ' daughter Antiope , who bore Amphion and Zethus to Zeus . Hyperes ' daughter Arethusa slept with Poseidon and was changed to a spring in Euboea , but not before bearing Abas , the eponym of the Abantes . His line is traced down to Elephenor , leader of the Abantes in the Trojan War . Sterope lay with Ares and bore Oenomaus , but it is possible that this union was delayed to book four as part of the section treating the family of Pelops and Oenomaus ' daughter Hippodameia .

 In between the Argo and the Trojan War , there was a generation known chiefly for its horrific crimes . This includes the doings of Atreus and Thyestes at Argos . Behind the myth of the house of Atreus ( one of the two principal heroic dynasties with the house of Labdacus ) lies the problem of the devolution of power and of the mode of accession to sovereignty . The twins Atreus and Thyestes with their descendants played the leading role in the tragedy of the devolution of power in Mycenae .

 Osiris 's death is followed either by an interregnum or by a period in which Set assumes the kingship . Meanwhile , Isis searches for her husband 's body with the aid of Nephthys . When searching for or mourning Osiris , the two goddesses are often likened to falcons or kites , possibly because kites travel far in search of carrion , because the Egyptians associated their plaintive calls with cries of grief , or because of the goddesses ' connection with Horus , who is often represented as a falcon . In the New Kingdom , when Osiris 's death and renewal came to be associated with the annual flooding of the Nile that fertilized Egypt , the waters of the Nile were equated with Isis 's tears of mourning , or with Osiris 's bodily fluids . Osiris thus represented the life @-@ giving divine power that was present in the river 's water and in the plants that grew after the flood .
