I see crowds of people, walking round in a ring.
There is a Tarot card in the Rider-Waite deck called Judgment (XX in the Major Arcana), which has six people ‘ringed’ around an angel blowing a trumpet. It seems to refer to The Last Judgment.
This image may also refer to the cycle of destruction exemplified in the first stanza of the poem (and which Madame Sorostris has just replicated in the fortune she has told for the narrator?).
More immediately, the image relates to the flowing “crowd” in the following stanza, shuffling drearily through the London streets. Perhaps Eliot is epitomizing human ignorance, anomie, or ineffectuality.
