Allegorical means telling one story so as to stand for another meaning. An allegorical figure, allegorical reading, read it allegorically.
The difference from a symbol is scale, since an allegory sustains the second meaning through the whole work rather than at one point. Writers often deny an allegorical reading of their own books, and readers ignore them.
