When we read the two poetical works 『Candlelight』 and 『Sad pastoral song』, we can find the vocabulary which are very frequently used, among them, 'mountain' and 'bird' can be said to be the key poetic words. The poet personifies the two objects, personification is interpreted as the most clear ontological metaphor in the Cognitive Poetics. This manuscript contemplates metaphor structure which 'mountain' and 'bird' form and blending space which is formed by that.
'Bird' forms blending space by metaphor structure as follows, which is established as the poet's objective correlative. “Forest is mother's knee, I am small and commendable being, I am brilliant, green and dream an endlessly deep dream. Birds can fly freely. They can go to anywhere they want, I'm not free, I'm not satisfied with present situation, The space which poetic narrator wishes is the forest, Forest is like the mother, It can embrace everything, Forest is the ideal world, Poetic narrator wants to fly freely to the ideal world, ······.”Blending space of 'mountain' is as follows. “I go to search the mountain, Warm moonlight infiltrates into the mountain, Mountain is a generous and great being. Mountain embraces, brings up, and protects. Mountain is the mother. Mountain is fine, calm and noble than the ancient times, Mountain is a being that embraces and protects. Mountain is old. Mountain meditates by closing its eyes, Mountain observes. Mountain is the absolute being,······.”Blending space has self revelation structure, therefore, the mixed space of 'bird' and 'mountain' can be more extended along with readers' background knowledge.
