For a sick person, seeing it in a dream indicates health and a well-proportioned figure, covering the face with hair [a beard] or the body with clothing. It may indicate cutting off despair [ās, "myrtle," / iyās, "despair"] of what one hopes to obtain. It is the plant called marsīn. It is also said to be a man who keeps his covenants. Whoever, man or woman, sees a wreath of myrtle on his head, it is a spouse who will remain long, or a lasting wife; likewise smelling it. Whoever sees it, it is a lasting good. If he sees that he is planting myrtle, he will manage his affairs with careful planning. Myrtle signifies lasting prosperity, office and lasting relief. Myrtle may also indicate wealth.
