The boatman speculates to his acquaintance that the body of the drowned man "will be swept up that way when the tide comes in about one." Gifford’s note makes clear that Joyce had consulted his tide tables: “High tides in Dublin, 16 June 1904, were at 12:18 AM and 12:42 PM.” In Proteus, which takes place between 11:00 and 1:00, Stephen is present on Sandymount Strand, the long tidal flat that extends from Kingstown to the Pigeon House off Dublin, to “see the tide flowing quickly in on all sides, sheeting the lows of sand.”

View across Sandymount Strand to the Poolbeg Generating Station, next to the now-decommissioned Pigeon House generating station of Joyce's day. Stephen walks on these wide tidal flats in Proteus. Source: lostchildreninthewilderness.wordpress.com.
