During one of the fantasy scenes in “Circe,” Leopold Bloom’s eccentric Hungarian grandfather Lipoti Virag pops into Bella Cohen’s brothel through a chimney, wearing Cashel Farrell’s monocle and a brown macintosh (a reference to the man in the macintosh). He talks about sex in a sterile, scientific way and gives anatomical descriptions of the prostitutes Zoe Higgins, Kitty Ricketts, and Florry Talbot. He represents Bloom’s rationality, prudence, and worldly curiosity, but his obsession with sex also points to Bloom’s concern about his ability to carry on his bloodline.
