The Arno at dusk

"The emperor's gaze traveled past the peacock and the lake, past the court of Herat and the lands of the fierce Turk and rested on the spives and domes of an Italian city far away. 'Imagine a pair of woman's lips,' Mogor whispered, 'puckering for a kiss. That is the city of Florence, narrow at the edges, swelling at the center, with the Arno flowing through between, parting the two lips, the upper and the lower. The city is an enchantresss. When it kisses you, you are lost, whether you be a commoner or a king.'"
