Editing Isis (section)

====Sky goddess====
Many of the roles Isis acquired gave her an important position in the sky.{{sfn|Wilkinson|2003|p=147}} Passages in the Pyramid Texts connect Isis closely with [[Sopdet]], the goddess representing the star [[Sirius]], whose relationship with her husband [[Sah (god)|Sah]]—the constellation [[Orion (constellation)|Orion]]—and their son [[Sopdu]] parallels Isis's relations with Osiris and Horus. Sirius's [[heliacal rising]], just before the start of the [[Flooding of the Nile|Nile flood]], gave Sopdet a close connection with the flood and the resulting growth of plants.{{sfn|Griffiths|1980|pp=12–14, 157–158}} Partly because of her relationship with Sopdet, Isis was also linked with the flood,{{sfn|Žabkar|1988|p=114}} which was sometimes equated with the tears she shed for Osiris.{{sfn|Tobin|2001|p=466}}

By Ptolemaic times she was connected with rain, which Egyptian texts call a "Nile in the sky"; with the sun as the protector of Ra's barque;{{sfn|Žabkar|1988|pp=43–44, 81–82}} and with the moon, possibly because she was linked with the Greek lunar goddess [[Artemis]] by a shared connection with an Egyptian fertility goddess, [[Bastet]].{{sfn|Delia|1998|pp=546–547}} In hymns inscribed at Philae she is called the "Lady of Heaven" whose dominion over the sky parallels Osiris's rule over the Duat and Horus's kingship on earth.{{sfn|Žabkar|1988|pp=52–53}}
