When Stephen thinks "I am here" at the beginning of Proteus, he is standing somewhere on "Sandymount strand," the beach and tide flats east of the suburb of Sandymount on Dublin's southeast periphery. The action of Nausicaa takes place on the same stretch of shoreline. And both episodes of Ulysses invite comparison with the passage at the end of Part IV of A Portrait of the Artist in which Stephen walks along a beach on the north side of the Liffey, near Dollymount.
