‘The Letter and the Cosmos is hugely stimulating to read… This is a wide ranging, consistently engaging work of synthetic scholarship from which no one will fail to come away enriched.’- Robert J. Mayhew (Journal of Historical Geography vol 58:2017) ‘The Letter and the Cosmos makes a positive contribution not only for specialists searching for an excellent sweeping over view, but general readers who want a fun read that they cannot put down and from which they will gain insights. Highly recommended.’- David B. Levy (Canadian Journal of History - vol 53:01:2018) "This book’s clear style and helpful illustrations make it engaging for specialists and non-specialists alike…[It] offers an insightful and valuable account of how the alphabet has been understood historically, from the Greeks to the present day, and in contrast to other writing systems."- David Watt, University of Manitoba (University of Toronto Quarterly, vol 87 3, Summer 2018)
