How does Ann Ward Radcliffe use imagery in The Mysteries of Udolpho?

Example of Imagery:

"In the evening, Madame Montoni, who, during the day, had observed a sullen silence towards her husband, received visits from some Venetian ladies, with whose sweet manners Emily was particularly charmed. They had an air of ease and kindness towards the strangers, as if they had been their familiar friends for years; and their conversation was by turns tender, sentimental and gay. Madame, though she had no taste for such conversation, and whose coarseness and selfishness sometimes exhibited a ludicrous contrast to their excessive refinement, could not remain wholly insensible to the captivations of their manner."
