this mughal jade cup, it's "瓜瓣瓢" or "瓜辨瓢"? this week, the christie's have an auction of this jade cup:

i suspected this one is the object of emperor 乾隆's poem 痕都斯坦玉羊頭瓜辨瓢歌

my question is:
the poem title is 玉羊頭瓜辨瓢
is it an typo of 瓣?
cause, in the poem, the 5th verse mentioned 瓜分數瓣

鹿臺嘉産来遐陬
彼中良工細雕鎪
式異漢盃及商卣
瓢飲一具琢羙球
瓜分數瓣花葉浮
曲柄廻顧為羊頭
匪夷所思用意周
其脂非逺其性柔
東陵闗内伊誰候

any ideas?
Looks like it should be 瓜瓣瓢.


瓜瓣瓢 probably means a 瓢 made from 瓜瓣. In contrast, 瓜辨 is not a word (AFAIK).
See a printed version of 清・金士松《喬羽書巢詩集》 (https://ctext.org/library.pl?if=en&amp;file=105725&amp;page=51). Since your screenshot looks like it's from a handwritten version of 《御製詩四集》, I suspect that it's a handwriting error. Well, printing is less likely to introduce errors :)
