Tree tattoos have significant symbolic meaning depending on the type of tattoo depicted. The tree tattoo in the picture is a representation of the mighty oak. It symbolizes strength and courage. The ancient Romans thought oak trees attracted lightening and thereby connected the oak tree to the sky god, Jupiter and his wife, Juno, the goddess of marriage.
