Ankh was, for the ancient Egyptians, the symbol (the actual Hieroglyphic sign) of life but it is an enduring icon that remains with us even today as a Christian cross. It is one of the most potent symbols represented in Egyptian art, often forming a part of decorative motifs.
The ankh seems at least to be an evolved form of, or associated with the Egyptian glyph for magical protection, sa. However, what the sign itself represents is often disputed. For example, Sir Alan Gardiner thought that it showed a sandal strap with the loop at the top forming the strap, but if so, the symbolism is obscure and so his theory has found little real favor early on. However, this interpretation seems to have received some acceptance among modern writers. It would seem that the ancient Egyptians called that part of the sandal 'nkh (exact pronunciation unknown). Because this word was composed of the same consonants as the word "life", the sign to represent that particular part of the sandal, was also used to write the word "life".
Another theory holds that the ankh was symbolic of the sunrise, with the loop representing the Sun rising above the horizon, which is represented by the crossbar. The vertical section below the crossbar would then be the path of the sun
The ancient gods of Egypt are often depicted as carrying ankh signs. We find Anqet, Ptah, Satet, Sobek, Tefnut, Osiris, Ra, Isis, Hathor, Anibus and many other gods often holding the ankh sign, along with a scepter, and in various tomb and temple reliefs, placing it in front of the king's face to symbolize the breath of eternal life. During the Amarna period, the ankh sign was depicted being offered to Akhenaten and Nefertiti by the hands at the end of the rays descending from the sun disk, Aten. Therefore, the ankh sign is not only a symbol of worldly life, but of life in the netherworld.
Therefore, we also find the dead being referred to as ankhu, and a term for a sarcophagus was neb-ankh, meaning possessor of life. (Source: touregypt.net)
