His fifth collection, The President of Planet Earth, must be one of the most formally diverse books of recent years: its 167 pages contain everything from sestinas to classical translations to Gaelic concrete poems. An invigorating cacophony of voices, the book’s wit, intellectual curiosity, and combination of historical perspectives with close attention to the present moment—as in the sonnet sequence, spoken by Robert Fergusson and written in a form of Scots, which considers the recent Scottish independence referendum—bring Edwin Morgan to mind. And it’s always good to have Edwin Morgan brought to mind.
