The scene is thus: in twelfth-century Cairo, emissaries of the Crusader King Amalric of Jerusalem, accompanied by that Falstaffian rogue, Giles Hobson – perhaps the most unique protagonist Howard ever created – have been granted an audience with the reclusive Fatimid Caliph of Egypt. Their escort is the wily vizier, Shawar …

At the gates of the Great East Palace the ambassadors gave up their swords, and followed the vizier through dim tapestry-hung corridors and gold arched doors where tongueless Sudanese stood like images of black silence, sword in hand. They crossed an open court bordered by fretted arcades supported by marble columns; their ironclad feet rang on mosaic paving. Fountains jetted their silver sheen into the air, peacocks spread their iridescent plumage, parrots fluttered on golden threads. In broad halls jewels glittered for eyes of birds wrought of silver or gold. So they came at last to the vast audience room, with its ceiling of carved ebony and ivory. Courtiers in silks and jewels knelt facing a broad curtain heavy with gold and sewn with pearls that gleamed against its satin darkness like stars in a midnight sky. While The Arabian Nights could easily have inspired Howard’s sumptuous vision in the above passage, it is in fact rigorously historical – the details recorded at Amalric’s behest by his friend and confessor, Archbishop Guillaume de Tyr, in his Latin history of the Kingdom of Jerusalem, Historia Rerum in Partibus Transmarinis Gestarum (A History of Deeds Done Beyond the Sea). The Historia was rare in the 1930s – a modern English translation did not come out until 1943 – and only slightly less rare today.
