London Bridge Is Falling Down [SEP] Viking attack explanation
One hypothesis of origin is that the rhyme relates to the supposed destruction of London Bridge by Olaf II of Norway in 1014 (or 1009). The nineteenth-century translation of the Norse saga the "Heimskringla", published by Samuel Laing in 1844, included a verse by Óttarr svarti, that looks very similar to the nursery rhyme: London Bridge is broken down. — Gold is won, and bright renown. Hild is shouting in the din! Odin makes our Olaf win! However, modern translations make it clear that Laing was using the nursery rhyme as a model for his very free translation, and the reference to London Bridge does not appear at the start of the verse and it is unlikely that this is an earlier version of the nursery rhyme.
