Sun Horse, Moon Horse
Rosemary Sutcliff
 The story revolves around Lubrin Dhu, a younger son of the chieftain, who takes after the Little Dark People who predated the Celtic settlers of the Iceni tribe; and whose name "Dhu" is related to Gaelic "Dubh", reflecting his darker appearance. Much is made of cultural differences between the reigning Celts, who are associated with fair hair and skin, and the original Chthonic Little Dark People, who are associated with darker complexions and a closeness with the earth. This cultural contrast again comes to fore when the Iceni, being associated with the moon, are subjugated by the Attribates, who are associated with the Sun. Lubrin Dhu's upbringing allows the reader to witness the culture of his people, from a somewhat "outside" point of view, as he is considered different to his people, on account of his darker color, reserved personality, and attraction to art. His people are matrilineal, with leadership going to the husband of Lubrin's sister. His father's status as chieftain derives from being married to the "woman of the tribe", and is intertwined with his duty to lay down his life for the tribe if needed, a duty which later descends to Lubrin Dhu. After their tribe is vanquished by the Attribates and their Strong Place occupied, Lubrin Dhu finds himself nominal leader of the survivors, his father and older brothers having been killed in battle. He strikes a bargain with the conquering chieftain, who will free Lubrin's people after completion of a monumental horse carved from the hillside. This figure becomes the Uffington White Horse. The novel's title reflects how the horse connects both the Solar attributes of the Attribates and the Lunar attributes of the Iceni, being considered an invocation to Epona. Lubrin Dhu ultimately voluntarily sacrifices himself for the consecration of the horse, fulfilling his duty as a chieftain's son, and offering a depiction of possible Celtic blood sacrifice. The theme of the novel revolves around conflicting cultures, and the duties assumed and performed by individuals within those cultures. The duties of a king are shown in many of her novels, including Sword at Sunset and The Mark of the Horse Lord, and have been credited as being influenced by James Frazer's The Golden Bough.
