The djed (π) is a tall pillar with a broad base, a narrow shaft and a distinctive capital consisting of four horizontal bands or discs stacked above each other, each slightly narrower than the one below. It is one of the most immediately recognisable symbols in the Egyptian hieroglyphic system β and one of the most debated in terms of its original physical referent.
As a hieroglyph, the djed means stability β djed in ancient Egyptian β and appears in texts and amulets as a wish for stability, endurance and permanence. But the djed is far more than a written symbol. It is a three-dimensional object, used in ritual, worn as an amulet, built into temple architecture and identified with specific deities. Its meanings accumulated over three thousand years of Egyptian religious practice, layering upon each other without replacing each other.
The earliest djed symbols, from the pre-dynastic period, may have represented a bundle of reeds or grain stalks tied together β a practical agricultural symbol of abundance and stability. By the Old Kingdom period, the djed was firmly identified with Osiris β specifically with his spine, the column of his being that held him upright and, after his resurrection by Isis, held him in eternal stability in the afterlife.
