This is the concluding line of the poem Martha by Walter De La Mare. In this line the poet describes what the effect of the stories of Martha lef on the mind of her children (the poet himself when he was a child). The stories created such a deep impression on the minds of the children that they seemed to be struck with awe and wonder. Their heart stopped beating and became still like motionless clouds high up in the sky. The silence and wonder of the distant past left them mute with wonder.
