In the past, there was a commander of the left guards called Ariwara no Yukihira. Hearing that there was a batch of good wine at his house, some people who were at court visited, among them the middle controller of the left, Fujiwara no Masachika, who served as guest of honor for the day.
Since Yukihira was a man of sensibility, he had placed flowers in a vase. Among the flowers was a striking and unusual bough of wisteria extending more than three feet in length. Those present composed poems with that as their topic.
