There was no "Dlugacz" on Dorset Street in 1904. Every other shopowner in Ulysses appears in the 1905 Thom's Directory, but Joyce named the butcher after a Jewish intellectual whom he knew in Trieste, because of the Zionism that Dlugacz passionately espoused. When Bloom infers in Calypso that the butcher is Jewish ("I thought he was"), and sees that the recognition is mutual, he appears to feel drawn to the man but saves his greeting for another day. Later in the chapter he dismisses Dlugacz's Zionism with the thought, "Enthusiast."
