The sacred tree in the Indo-European world

In Indo-European antiquity, much of the religious
and cultural imaginary of all these peoples saw in the
symbol of the tree and its fruit the arcane of
knowledge, starting from the Sycamore Tree 1 in
Egypt associated with the Goddess Isis, wife and
mother of the pharaoh always ready to offer the
hidden knowledge of things, giving the pharaoh the
sap of knowledge to drink, even the Acacia Tree
revered throughout the Mediterranean world for
being a symbol central resistance, even with the
Absence of rain the Acacia grows.
1 The sycamore begins to be mentioned in predynastic times in Ancient Egypt. Egypt is sometimes
mentioned as the "Country of Sycamores," and the tree was called the false fig or Egyptian fig. According to
Zohay and Hopf, the Egyptians were the only ones who cultivated this tree, very easy to reproduce by
cuttings. Due to its incorruptible wood, the Egyptians quickly related it to death and resurrection; hence,
they were planted near graves and coffins were built when possible with their soft and light wood. Amulets
were also made in the shape of their leaves.
