Hazel takes its name from the hazel tree, long associated in folk tradition with wisdom and protective qualities -- hazel wood was often used for divining rods and walking sticks. The name is commonly read as carrying a grounded, sheltering quality, wisdom understood as practical rather than purely intellectual.
Make the Sun, or any of the superiors to signify princes and great persons. Scribes and rusticks, [are shown by] the inferior planets, and chiefly the Moon. - William Lilly (1602.-1681.)
