This divine assemblage had a vague and changeable hierarchy. Gods with broad influence in the cosmos or who were mythologically older than others had higher positions in divine society. At the apex of this society was the king of the gods, who was usually identified with the creator deity. In different periods of Egyptian history, different gods were most frequently said to hold this exalted position. Horus was the most important god in the Early Dynastic Period, Ra rose to preeminence in the Old Kingdom, Amun was supreme in the New, and in the Ptolemaic and Roman periods, Isis was the divine queen and creator goddess. Newly prominent gods tended to adopt characteristics from their predecessors. Isis absorbed the traits of many other goddesses during her rise, and when Amun became the ruler of the pantheon, he was conjoined with Ra to become a solar deity.
