The Tat (Illustrations Nos. 63, 64, 65, Plate V) held a very important place in the religious services of the Egyptians, and formed the centre of the annual ceremony of the setting-up of the Tat, a service held to commemorate the death and resurrection of Osiris, this symbol representing the building-up of the backbone and reconstruction of the body of Osiris. In their services the Egyptians associated themselves with Osiris, through whose sufferings and death they hoped to rise glorified and immortal, and secure Everlasting Happiness. The four cross-bars symbolise the four cardinal points, and the four elements of Earth, Air, Fire, and Water, and were often very elaborately ornamented (see Illustration No. 64, Plate V, taken from an example at the British Museum). It was worn as a Talisman for Stability and Strength, and for Protection from enemies; also that all doors, (or opportunities,) might be open both in this life and the next. Moreover, a Tat of gold set in sycamore wood, which had been steeped in the water of Ankham flowers, was placed at the neck of the deceased on the day of interment, to protect him on his journey through the underworld and assist him in triumphing over his foes, that he might become perfect for ever and ever.
The Heart was believed to be the seat of the Soul, and Illustrations Nos. 67, 68, 69, Plate V, are examples of these Talismans worn to prevent black magicians from bewitching the Soul out of the body. The importance of these charms will be realised from the belief that if the Soul left the Heart, the Body would quickly fade away and die. According to Egyptian lore at the judgment of the dead the Heart is weighed, when if found perfect, it is returned to its owner, who immediately recovers his powers of locomotion and becomes his own master, with strength in his limbs and everlasting felicity in his soul.
