man in the moon, (no more than) the

A mythical figure, hence nothing, or a figment of the imagination. Mention of the man in the moon dates from the early fourteenth century. In Troilus and Criseyde Chaucer quotes, indirectly, a myth that a man who desecrated the Sabbath was banished to the moon. By the sixteenth century, however, this turn of phrase was linked with something so distant as to be unlikely (“as farre from her thought as the man that the rude people saie is in the moone,” Edward Hall, Chronicle of Richard III, ca. 1548).
