Chief Minister Yi and Academician Bak Call on Me Together — It was the twenty-fifth day of the seventh month. The bongsang flowers (鳳翔花) were then in full bloom in my garden, so I had the Venerable Yeong call out a rhyme and compose at the run of his brush, and I too answered him there and then at the run of my brush李相國，朴學士同訪。是七月二十五日也。時家園鳳翔花盛開。唱韻使英上人走筆賦之。予亦卽席走筆和示。

Dongguk Isangguk Jip (Collected Works of Minister Yi of the Eastern Country) Latter Collection, Book 7 The collected writings of Yi Gyubo of Goryeo, gathered and cut in woodblock by his son Yi Ham in 1241 and revised and enlarged by his grandson Yi Ikbae in 1251. It holds poems and rhapsodies, memorials and reports sent up to the king, records written for temples and pagodas, stele and tomb inscriptions, letters and prefaces, and the state letters that passed to and from the Mongols during the invasions. The Lay of King Dongmyeong, which sings the founder of Goguryeo, stands in volume 3 of the first collection, and the daily life of a man who called himself the White Cloud Layman — with his wine, his zither and his verse — fills the later collection. The book closes with the last poem he wrote as his eyes failed and he laid down the brush, and with the dirge and tomb inscription others made for him after his death.
