Foot p.188) were executed by the Mahieu Aesop binder. This binder also worked for Mahieu's friend, fellow bibliophile, and previous Treasurer of France, Jean Grolier. A twin of the present binding, covering a 1502 Aldine Catullus, survives at Trinity College Dublin (Hobson no. 27). See G.D. Hobson, Maioli, Carnevari, and others, London: 1926; H.
