In her web's centre, shakt with every winde,
Moves in an instant if the buzzing flie
Stir but a string of her lawn canapie.

First Week, Sixth Day. Compare: "Much like a subtle spider which doth sit In middle of her web, which spreadeth wide; If aught do touch the utmost thread of it, She feels it instantly on every side", John Davies, The Immortality of the Soul.
