When the Emperor held Constant in his power, he pondered deeply how he might slay him, and no man speak a word. It chanced at this time that the Emperor had business which called him to the frontier of his realm, a very long way off, a full twelve days' journey. He set forth, carrying Constant in his train, yet brooding how to do him to death; and presently he caused letters to be written in this wise to the castellan of Byzantium.
"I, the Emperor of Byzantium, and lord of Greece, make him, the governor of my city, to know that as soon as he shall read this letter he shall slay, or cause to be slain, the bearer of this letter, forthwith, upon the delivery thereof. As your proper body to you is dear, so fail not this command."
Such was the letter Constant carried, and little he knew that it was his death he held in hand. He took the warrant, which was closely sealed, and set out upon his way, riding in such manner that in less than fifteen days he reached Byzantium, the town we now call Constantinople. When the varlet rode through the gate it was the dinner-hour, so (by the will of God) he thought he would not carry his letter to table, but would wait till men had dined. He came with his horse to the palace garden, and the weather was very hot, for it was near to Midsummer day. The pleasaunce was deep and beautiful, and the lad unbitted his horse, loosened the saddle, and let him graze; then he threw himself down beneath the shelter of a tree, and in that sweet and peaceful place presently fell sound asleep.
Now it happened that when the fair daughter of the Emperor had dined, she entered the garden, and with her four of her maidens, and soon they began to run one after the other, in such play as is the wont of damsels when alone. Playing thus, the fair daughter of the Emperor found herself beneath the tree where Constant lay sleeping, and he was flushed as any rose. When the Princess saw him, she would not willingly withdraw her eyes, saying to her own heart that never in her life had she beheld so comely a person. Then she called to her that one of her companions who was her closest friend, and made excuses to send the others forth from the garden. The fair maiden took her playfellow by the hand, and brought her towards the slumbering youth, saying—
"Sweet friend, here is rich and hidden treasure. Certes, never in all my days have I seen so gracious a person. He is the bearer of letters, and right willingly would I learn his news."
The two damsels came near the sleeping lad, and softly withdrew the letter. When the Princess read the warrant she began to weep very bitterly, and said to her companion, "Certainly this is a heavy matter."
"Ah, madame," said her fellow, "tell me all the case."
"Truly," answered the Princess, "could I but trust you fully, such heaviness should soon be turned to joy."
"Lady," replied she, "surely you may trust me; never will I make known that which you desire to be hid."
