As Kingfishers Catch Fire
Gerard Manley Hopkins · 1918
1As kingfishers catch fire, dragonflies draw flame;
2As tumbled over rim in roundy wells
3Stones ring; like each tucked string tells, each hung bell's
4Bow swung finds tongue to fling out broad its name;
5Each mortal thing does one thing and the same:
6Deals out that being indoors each one dwells;
7Selves — goes itself; myself it speaks and spells,
8Crying What I do is me: for that I came.
9I say more: the just man justices;
10Keeps grace: that keeps all his goings graces;
11Acts in God's eye what in God's eye he is —
12Christ — for Christ plays in ten thousand places,
13Lovely in limbs, and lovely in eyes not his
14To the Father through the features of men's faces.
