The sycamore: representation of the Tree of Life
In various parts of the ancient world, trees were associated with different gods, and Egypt was certainly no exception. We do not know of any tree, or indeed any other vegetation in Egypt that was honored as specific gods as were bulls or rams, for example. Nevertheless, various vegetations were linked to the gods and goddess in one way or another, or generally to the Egyptian religion and more particularly to the afterlife.
Several deities were associated with trees, a rare commodity in Egypt. Horus was associated with the acacia tree, while Osiris and Ra were linked to the willow and sycamore respectively. Osiris was sheltered by a willow tree after being killed, and for example, the Book of the Dead describes two "turquoise sycamores" growing at the point on the eastern horizon where the sun-god rises each morning. Re was also associated with the frozen tree. In addition, Wepwawet was associated with the Tamarisk, and the symbol of the god Heh was a palm branch, not surprisingly, we have both Thoth and Seshat, the two deities associated with writing, inscribing the leaves of the ished (or persea) tree with the Royal Title and the number of years of the reign of the pharaoh.
However, none of these deities were as associated with trees as a number of female deities
The sycamore tree was of particular importance in Egyptian religion. It was the only indigenous tree of useful size and sturdiness in Egypt, and perhaps most significantly, grew most often at the edge of the desert, which would also have placed it near or in necropolises.
