I will never visit Noah's Ark - it would be disastrous for my blood pressure
I don't think I could resist the temptation to deface this sign. I quite like the poem as an allegory (although I'm not a great fan of Blake). But after the line 'Did he who made the lamb make thee?' there is a nice space in which to write, paint and inscribe
How can any poem in the world to contain an error????? Despite my not very good understanding of English, I would say that none of your signage pics have any important or really noticeable error...
The poem is by William Blake, rather than anyone at Noah's. In several places it's been inaccurately copied, giving a version that often butchers the meaning of the original.
As for whether these errors are important or noticeable, they're obviously on a scale. Some are severely nitpick-y, whilst others are massive and (in my opinion) unacceptable. The latter makes one more inclined to point out the former, as Chlidonias and I discussed here: http://www.zoochat.com/211/spot-error-s-463170/.
It's not a poem I'm massively familiar with, but I was interested and looked it up. There is the odd place where ! and ? have been interchanged, which obviously gives a different reading. One very notable difference is that the last stanza should read:
Tyger Tyger burning bright,
In the forests of the night:
What immortal hand or eye, Dare frame thy fearful symmetry?
...which is a definite shift of emphasis. Basically my understanding is that Blake was recognising that any creator that made something as 'terrible' as the tiger would have to be pretty darn terrifying themselves. Shifting from 'dare' to 'could' makes it much more a question of simple capacity than ferocity, and therefore could be taken to be giving the creator a more favourable presentation.
That said, it's quite possibly just someone typing it out and not paying attention somewhere along the lines..!
