Pictogram (象形) – a deer. Current form is highly abstracted – legs have transformed to 比 – note grouping of front and rear legs, which are bent – head has transformed to middle component (similar to 凸/曲), while antlers on top and extended lip/mouth on left transformed into 广. This simplification occurred during seal characters.
Contrast the very different development of 馬 (“horse”), and the hybrid simplification in 𢊁 (“bison”) (as in 薦), which has the head of 鹿 but the legs of 馬 (灬).
Yamadori no horo to naku o kikite mo, chichi ka haha ka to utagahi, mine no kasegi no chikaku naretaru ni tsukete mo, yo ni tōzakaru hodo woshiru.
Hearing the horo call of the mountain pheasant, wondering if it were my father or mother [calling from beyond the grave], and seeing how the deer on the ridge are so tame that they come close by, all of it shows me how far away I am from the world.
