monument has two sides, referred to by the architects as the reverse and the obverse of the work, which they likened to the two sides of a coin. These two aspects represent the prologue and the epilogue of war. Each side features a relief carved from Angaston marble and framed by the "rough-hewn" arch carved out of marble from Macclesfield, while the granite steps leading up to the monument are constructed of Harcourt granite, as specified in the original proposal. (The architects had preferred the local West Island granite, but acknowledged that the Harcourt granite was "the best available" unless the government would agree to reopen the quarry on West Island). The materials were chosen in order to provide continuity with Parliament House, located a short distance away along North Terrace. To represent the prologue to the war, the obverse of the monument (the side facing North Terrace) features a relief of the Spirit of Duty appearing as a vision before the youth of South Australia, represented in the work by a sculptural group consisting of a girl, a student and a farmer abandoning the "symbols of their craft". The three are depicted in normal dress, as they are not yet soldiers and are currently unprepared for the war that is to come, and they are facing away from the world as they look to the vision before them. In Bagot's original plan, submitted for the 1924 competition, there was to be but a single nude figure kneeling before the vision (for which Bagot posed while in Europe), but Laybourne-Smith's 1926 submission became grander in its scope. In addition, Bagot's original designs were naturalistic, with the Spirit of Duty depicted as a female figure, but under Hoff's direction the figure was changed to male, and the style of the reliefs was changed to Art Deco—a "radically new" art style for Australia at the time. Hoff, however, presented the sculptural group in the original naturalistic style, thus providing a "bridge between the Renaissance-style architecture and the Art Deco of the reliefs". On the reverse side of the monument, facing away from the traffic, is a relief carved into the marble representing the epilogue of the war and depicting the Spirit of Compassion as a winged spirit of womanhood bearing aloft a stricken youth. Beneath the figure is situated the Fountain of Compassion, the flow of water representing the "constant flow of
