Expositio perutilis in primam Fen quarti canonis Avicennae
A 1518 Lyons medical commentary by Johannes Arculanus on Avicenna's Canon, printed for the bookseller Vincentius de Portonariis and held in Yale's Cushing medical library. Its two pictures are printer's and owner's devices rather than text illustrations: a winged angel holding an open book inside a ruled border with a pair of shields, and a heraldic bookplate with a skull, laurel branch, and caduceus in ornamental scrollwork. A designer could take the framed emblem layouts, strapwork borders, and ribbon lettering as models for historic label design.
