Wallhall

• Valhalla: in Norse mythology, the afterlife where those slain in battle feast, fight, and prepare for Ragnarok, or the end of the world, when they will fight on the side of Odin

• G Walhall: German form of Valhalla; Wotan's fortress in Richard Wagner's operatic tetralogy Der Ring des Nibelungen

• Wall hall → a gallery

• Pall Mall: a street in London

• FW 005.30-006.07: the passage in parentheses seems to represent the various noises of morning rush-hour in Paris (where Joyce wrote FW) and Dublin (where the novel is set), as though the window or curtain (in Joyce's apartment and in HCE's bedroom) is opened at this point, allowing the street noises to "invade" the narrative
