At the end of Lotus Eaters Bloom sees that the southeastern gate of Trinity College is manned by an attendant in a gatehouse: "There's Hornblower standing at the porter's lodge." At the end of Wandering Rocks this man is seen again in the same spot, saluting the viceregal cavalcade as it passes by: "Deep in Leinster street by Trinity's postern a loyal king's man, Hornblower, touched his tallyho cap." The Trinity porters were, as the word suggests, gatekeepers, but they also maintained order and decorum throughout the campus. They dressed in a strangely distinctive style that made them look like country gentlemen on a fox hunt—hence "tallyho," and probably also Joyce's choice of a surname.

Crowds gathered on Trinity College roofs to celebrate the British victory in WWI, in the same place where Anzac snipers had effectively operated in 1916.
