How does H.L. Mencken use imagery in A Mencken Chrestomathy?

Imagery:

"To the gods who run the cosmos, disease and health probably look pretty much alike. I am not, of course, privy to the secret lucubration of Yahweh, but it is certainly imaginable that a hearty, incandescent boil gives Him quite as much satisfaction as a damask check, and maybe a great deal more."
