Nevertheless, among the names given to them, though never all at once, there were either three, four, or seven Hesperides. Apollonius of Rhodes gives the number of three with their names as Aigle, Erytheis and Hespere (or Hespera). Hyginus in his preface to the "Fabulae" names them as Aegle, Hesperie and *aerica. In another source, they are named Ægle, Arethusa and Hesperethusa, the three daughters of Hesperus. Hesiod says that these "clear-voiced Hesperides", daughters of Night, guarded the golden apples beyond Ocean in the far west of the world, gives the number of the Hesperides as four, and their names as: Aigle (or Aegle, "dazzling light"), Erytheia (or Erytheis), Hesperia ("sunset glow") whose name refers to the colour of the setting sun: red, yellow, or gold and lastly Arethusa. In addition, Hesperia and Arethusa, the so-called "ox-eyed Hesperethusa". while Fulgentius named them as Aegle, Hesperie, Medusa and Arethusa. An ancient vase painting attests the following names as four: Asterope, Chrysothemis, Hygieia and Lipara; on another seven names as Aiopis, Antheia, Donakis, Calypso, Mermesa, Nelisa and Tara. A Pyxis has Hippolyte, Mapsaura, and Thetis. Petrus Apianus attributed to these stars a mythical connection of their own. He believed that they were the seven Hesperides, nymph daughters of Atlas and Hesperis. Their names were: Aegle, Erythea, Arethusa, Hestia, Hespera, Hesperusa and Hespereia.
