Joannis Herculani in Avicennae quarti canonis fen in qua de febribus agitur, ... explicatio...
A 1560 Venetian medical commentary by Giovanni Arcolani on Avicenna's Canon, set in dense black-letter-style roman type in two columns with running headers reading HERCULANUS and DE FEBRIBUS. The pages are almost wholly text, with only occasional small woodcut initials and a single small figure, so a designer would take from them mainly the rhythm of dense justified text blocks, ornamental capitals and the period page layout.
