This little bit of doggerel was hummed by Slughorn while drinking with Hagrid after Aragog's burial.
The translators all seem to assume that this is a serious piece of verse and try to improve it in various small ways, not realising that it is meant to be ridiculous.
The name Odo is not an uncommon one historically, although it is not clear whether Rowling's "Odo the Hero" is modelled on any of them. There is actually a page on the Internet that looks at Odo's through history -- related not to Harry Potter but to Odo in Star Trek! See also Odo the Great of Aquitaine.
And Odo the hero, they bore him back home
|Yīngxióng Àoduō bèi tái huí gùxiāng,
Tái dào tā érshí shúxī de dìfang,
Màozi fān-guolai, rùtǔ ānzàng,
Mózhàng zhé liǎngduàn, duōme bēishāng.
Short and sweet, like the English, and rhyming to boot!
Yīngxióng Ōuduō, tāmen dài tā fǎnhuí jiāxiāng,
Fǎnhuí tā cóng xiǎo shēngzhǎng de dìfang,
Tāmen ràng tā zài cǐ chángmián, bànsuí-zhe tā nà fǎn-guolai de wūmào,
Hé duàn chéng liǎngjié de mózhàng, zhè jǐngxiàng héděng qīliáng.
This version takes itself more seriously, but the effect is, if anything, more ridiculous. The last line, in particular, changes the very plain English words 'which was sad' into '這景象何等淒涼' zhè jǐngxiàng héděng qīliáng, meaning 'how bleak was this scene!' The use of language is much more literary and high-falutin' than the English.
For all but the third line the verse rhymes. However, there is a rather jarring discrepancy in the length of lines.
|Kakushite minna wa eiyū no, Odo o ie e to hakobi-komu
Sono ie wa Odo ga sono mukashi, seinen no hi o sugoshita ba
Odo no bōshi wa ura-gaeshi, Odo no tsue made mapputatsu
Kanashii omei no eiyū no, Odo wa sono ie ni hōmuraru
The Japanese version adds the words 悲しい汚名 kanashii omei 'sad disgrace' at the last line, making Odo into a 'hero in sad disgrace', presumably because his hat is inside out and his wand is broken in two.
| Và vị anh hùng Odo được đưa về nhà
Nơi chàng quen thuộc từ thời trai trẻ,
Họ đặt chàng yên nghỉ với cái nón lật ngược.
Và cây đũa phép bị bẻ gãy đôi, ấy mới buồn.
The Vietnamese is relatively close to the English.
