The Right state: it is certainly possible to say that the ‘bridge at Nagara’ has ‘rotted’ (kutsu), but there are, we think, no other examples of it ‘ceasing’ (tayu). The Left state: we wonder about the appropriateness of saying ‘love not a trace’ (koi ni ato nashi).
In judgement: both poems refer to ‘the bridge at Nagara’ and, as has been mentioned by the Gentlemen of the Right in their criticism, the Left uses ‘has ceased to be, yet’ (taeshikado); there are many poems using ‘rotted’, because this is what happens to the pillars of bridges. After this bridge ceased to be, the pillars would still be rotting away. If you have the bridge ‘being built’ (tsukuru nari), why would you not then have it ‘ceasing’? That being said, I am only accustomed to hearing ‘bridge pillars’ (hashibashira), and having only ‘pillars’ (hashira) sounds completely lacking in logic. The Right’s poem uses ‘love not a trace’ (koi ato nashi): it is entirely natural for a variety of different things not to leave a trace. The current criticism must be due to there not being a prior example of this usage, but it is particularly difficult to say this about the initial section of the poem. The Right wins.
