How does Muriel Spark use imagery in Loitering with Intent?

Imagery:

"Fleur was the name hazardously bestowed at birth, as always in these cases before they know what you are going to turn out like. Not that I looked too bad, it was only that Fleur wasn't the right name, and yet it was mine as are the names of those melancholy Joys, those timid Victorias, the inglorious Glorias and materialistic Angelas one is bound to meet in the course of a long life of change and infiltration; and I once met a Lancelot who, I assure you, had nothing to do with chivalry."
