This haiku was created based upon the hokku of Basho MATSUO's "Nozarashi kiko," 'Kyoku kogarashinomiwa Chikusai ni nitaruya' (I'm wandering around making haiku, so I am like crazy Chikusai, a hero of a story), which indicates that Kyoshi compared Seigetsu with Basho.
この句が松尾芭蕉『野ざらし紀行』の発句「狂句木枯の身は竹斎に似たる哉」を踏まえている点から、虚子が井月を芭蕉と比較していたことが分かる。
