In Sirens, Bloom thinks of meeting Marion Tweedy at
that house in 1887: "First night when first I saw her at Mat
Dillon's in Terenure. Yellow, black lace she wore. Musical
chairs. We two the last. Fate. After her. Fate." Oxen of
the Sun, on the other hand, recalls that meeting, and
the first meeting of Stephen and Bloom, as having taken place
in "the wellremembered grove of lilacs at Roundtown," and Ithaca
confirms this location, noting that Stephen and Bloom met "in
the lilacgarden of Matthew Dillon's house, Medina Villa,
Kimmage road, Roundtown, in 1887."
The book's seemingly contradictory locations of Mat Dillon's
house are not in fact so. Gifford notes that "By 1904
Roundtown had been renamed Terenure" (573). Bloom uses the
contemporary name when he thinks of meeting his future wife.
The narrative uses the name that was in force at the time of
the meeting.
