Ekphrasis, self-Googling, and Sotheby’s all collide in this excerpt from Ben Doller’s long poem, “Thend.” In sonnets that rat-a-tat-tat like an auctioneer’s call, Doller discovers his doppelganger, considers his mortality, and learns that “it’s hard to say when one’s saying goodbye.” The results are stunning and funny and self-aware.
