At the end of day the caliph Haroun reclines and smokes in his palace, with his servant Splendiano; an off-stage chorus sing. The slave-girl Djamileh passes through the room unseen by Haroun, gazing tenderly at him. Splendiano is looking over his master’s accounts when Haroun asks Splendiano where Djamileh is – and is told that she is near at hand, still in love. He remarks also that she will be disappointed as her month as lover to the sultan is nearly finished and she will be replaced. Haroun denies that he is in love with her and demands that she be sent away and a new girl brought. Splendiano confides that he is taken with Djamileh.

Splendiano asks the merchant to replace the dancer with Djamileh, while being certain that she will soon be his. Veiled, Djamileh enters in the dancer’s costume and, shy and nervous, makes to leave. Haroun, whose interest is now aroused, sends Splendiano to take his place at the games table. Djamileh cries, but Haroun consoles her. As moonlight illuminates the room, Haroun recognizes her and begins to realize that she loves him. He tries to resist his
