The Dragon Swallows the Carriage

From C7.4, The Dragon of the Third Stage. It illustrates C7.4.31–36:

C7.4.31
The horses strained to flee the dragon’s force,But it sucked in the carriage and each horse.
C7.4.32
Inside the box, the prince grew stern and grim;The swords lodged in the maw surrounding him.
C7.4.33
Blood like a sea poured from its wounded maw;The swords stayed fixed between its throat and jaw.
C7.4.34
Those swords had made its mouth a sheath of pain;It could not loose them; strength began to wane.
C7.4.35
Then from the box the gallant warrior rose,And raised his sword to strike repeated blows.
C7.4.36
With lion’s strength he hacked the dragon’s brain,Till venom fumes arose across the plain.
