Right? And that's a weird part, too. In Browning's telling of the story, he said 3 children were left behind. The deaf child who couldn't hear the music, the lame child that couldn't follow and the blind child that couldn't see to follow.

Whether it was just 3 or not is questionable, but gives the impression that children with disabilities were left behind. Which is also a point of unanswered curiosity.
