Dark Emperor

Dark Emperor & Other Poems of the Night

Like Sidman's Caldecott Honor Book, Song of the Water Boatman and Other Pond Poems (2005), this picture book combines lyrical poetry and compelling art with science concepts. Here, poems about the woods at night reveal exciting biology facts that are explained in long notes on each double-page spread. In a poem about crickets, lines describe “the raucous scrape / of wing against wing,” while a prose passage explains that the cricket's wing has a serrated “file,” which the cricket rubs against a hard “scraper” on its other wing to attract a mate, creating a sound called “stridulation” that can swell to deafening levels. The facts are further reinforced in the accompanying picture, which shows the small file on a cricket's wing. In an opening note, Allen explains his elaborate, linoleum-block printmaking technique, and each atmospheric image shows the creatures and the dense, dark forest with astonishing clarity. Looking closely at a picture of a snail, for example, readers will see the physical detail, described in an adjacent poem, in the small animals' moist, sluglike bodies, “riding on a cushion of slime.” The thrilling title poem captures the drama of predator and prey: a mouse in the undergrowth flees an owl's “hooked face and / hungry eye.” A final glossary concludes this excellent, cross-curricular title.
