Before this, Delos - like Rhodes, the centre of the worship of the sun-god Helios, with whom Apollo was wrongly identified in later times - had been a barren, floating rock, but now became stationary, being fastened down by chains to the bottom of the sea.
The name of Re, the sun-god, was generally joined to Ammon, especially in his title as " king of the gods ": the rule of heaven belonged to the sun-god in the Egyptian cosmos, and this identification with Re was only logical for a supreme deity.
The movements of the sun, moon and five planets were regarded as representing the activity of the five gods in question, together with the moon-god Sin and the sun-god Shamash, in preparing the occurrences on earth.
Of the moon-god, and since, in an enumeration of the pantheon, Sin generally takes precedence of Shamash, it is in relationship, presumably, to the moon-god that the sun-god appears as the dependent power.
The name itself (= red) and the colour of the cattle suggest the fiery aspect of the disk of the setting sun; further, Heracles crosses Oceanus in the golden cup or boat of the sun-god Helios.
