“Maija Jansson’s beautifully illustrated book breathes new life into a field of study traditionally associated with dry and dusty antiquarianism […]. One of the highlights of Jansson’s book is the inclusion of fourteen color reproductions of the most visually exciting of these letters, which again invite us to appreciate royal correspondence of the early modern period as more than mere text: they were material objects and works of art, comprising a rich and varied range of visual semiotics about which, thanks to Jansson, we still have so much to learn.”

“Maija Jansson has uncovered not only a little-known source, but also a neglected culture of official communication, with a long tradition and an enduring set of conventions.”
