“ It is far more likely that Chaucer adopted the phrase from Dante, Purg. xix. 4. Fortuna maior was a figure in geomancy (cf. note to Cant. Tales, A 2045, in vol. v. pp. 82, 83) ; and this figure was like four points (or stars) arranged in a square, with two more points below it (like a four of diamonds above a two of the same) . The name was also bestowed upon a group of six stars that formed a figure roughly resembling the same, though one of the stars (as it were at the top left-hand corner) is a little out of place. ”
