“Brother-in-Arms” was not provided with an illustration by Mervyn Peake in my Folio Society Edition.
The slightly altered translations in my other two editions are given alongside the names or the respective artists.
This work describes the story of two inseparable knighthood friends who are parted when one goes off to war and the other is left as protector of the former’s wife. In the author’s lively language we are introduced to the enticing temptations resulting from this and to the guardian’s strenuous sacrificial efforts to resist.
These are the illustrations of Gustave Doré (The Brother-in-Arms);
and these of Jean de Bosschère (The Brothers in Arms).
