A Hundred Verses from Old Japan (The Hyakunin-isshu), tr. by William N. Porter, [1909], at sacred-texts.com
MY constancy to her I love
I never will forsake;
As surely as the Palace Guards
Each night their watch-fire make
And guard it till daybreak.
The author was the son of the Minister Yorimoto, and he lived during the latter part of the tenth century. The illustration shows the watchman outside the Palace tending his fire.
