Aspis, the aspen’s Greek name, means shield. These shields were imbued with additional magical, protective qualities to shield the bearer from psychic as well as physical harm. The magically protective nature of the “shield tree” extended to the general population too and, like the rowan tree, was a popular choice of tree to plant close to a dwelling.
