From the story The Quest of the Golden Fleece
The great gleaming dragon slid slowly from the tree, coil within coil, and, resting its terrible head on the bank of sleeping red poppies, slept for the first and last time in its life.
Only by the charms of Medea did Jason himself remain awake, and when he saw the dragon slept, he drew near and looked up at the shining Fleece.
Then Medea sprinkled the dragon with her magic brew, and whispered to Jason: ‘Climb! Climb swiftly up the coils of the back and take down the Fleece, for my charms will not hold it long!’
