In Knolles's work, the Sultan Mahomet conquers Constantinople in 1453 and captures a Greek Christian named Irene. He decides to take her as his mistress, and while pursuing her romantically he ignores his duties as a monarch. Soon, the kingdom is falling apart from neglect and the subjects begin to riot, so Mahomet kills Irene to prove his dedication to his people. Johnson alters the story to emphasise the theme of Irene's temptation. His Mahomet offers Irene a deal: if she becomes a Muslim, he will preserve her life and give her power at his court.IRENE:&lt;br&gt;Forbear — O do not urge me to my ruin!&lt;br&gt;MAHOMET:&lt;br&gt;To state and pow'r I court thee, not to ruin:&lt;br&gt;Smile on my wishes, and command the globe.&lt;br&gt;Security shall spread her shield before thee,&lt;br&gt;And Love infold thee with his downy wings.&lt;br&gt;("Irene" II. vii ll. 79–83)
