Sir Peter Teazle, as Thornton notes, is a character in Richard Brinsley Sheridan’s School for Scandal (1777). Mulligan seems to imply that Stephen's mother lost her mind toward the end of her illness: "She calls the doctor sir Peter Teazle and picks buttercups off the quilt. Humour her till it's over." But Ellmann suggests that when May Dedalus referred to “the dapper doctor” attending her by this name, it was not a sign of dementia. Rather, she was attempting “to be lighthearted” (135).
