 However, as far as the relationship with Strepponi proceeded, Phillips-Matz recounts that Verdi was "living in an apartment around the corner from Strepponi's house", that the news of this had reached Italy ("Verdi had been seen "chez" Strepponi"), and that, in writing the music for "Jérusalem", he had received her help to the extent that a handwritten love duet in the composer's autograph score contains alternative lines in her handwriting and in his.This is described by British music critic Andrew Porter as "one of the more romantic discoveries of recent years".Baldini tells us that "at the end of 1847 Verdi rented a little house in Passy, and went to live there with Giuseppina", but Phillips-Matz does not go so far, noting only that "he may have moved into her apartment or a separate apartment in her building", but later does confirm the move to Passy, dating it to June 1848.
