Close to the Quatrain in form. The rhyme is sŏn/yŏn; tones match except for the second line.
Attributed to Hae Chin in Shiga Ch'onghwa; Kim T’aejun (1905-1949) says it is the work of a Chinese poet, but there is no verification of the poet’s identity. Several versions of the poem, with minor variations, occur in the oral tradition, and it is commonly attributed to Kim Sakkat.
The hwan’gap was a celebration to mark one’s sixtieth birthday, a considerable feat of longevity in old Korea. Kim Sakkat composed the poem at one such hwan’gap feast. The first line enraged the sons of the man who was being honored; the second line had them smiling. The third line enraged them once again; and the fourth line left them smiling. The magic peach came once in a thousand years. To eat it was a guarantee of longevity.
That old man sitting over there is no man at all;
he’s an Immortal lately come from heaven’s door.
The seven sons sitting here are thieves;
they’ve stolen the magic peach and presented it at this hwan’gap feast.
