3.228

盲瞽（上盲字前第一卷已解下音古釋名瞽者眠也眠眠然二目平合如鼓皮因象為名說文目但有映從目從鼓會意字也）。

Blind (盲瞽: the first character, 盲, was already explained above in Fascicle 1; the second character has the sound of gu [古]. The Shiming says: “A blind person (瞽) has closed eyes; the two eyes are closed flatly shut like the skin of a drum (鼓), and it is named according to this image.” The Shuowen says: “The eyes merely have an outline.” It is formed from eye [目] and drum [鼓], an ideographic character).
