Joseph Cundall, A Brief History of Wood-engraving… (1895)
“ Another celebrated printer who enjoyed the patronage of the King was Robert Estienne, who, by some curious perversity, is frequently spoken of by English scholars and biographers as Robert Stephens, simply because, following the fashion of the day, he often latinised his name and signed Robertus Stephanus. Estienne was, next to Aldo Manuzio of Venice, the most learned of printers, and deserves to be held in due reverence. The most important illustrated book he published was 'The Lives of the Dukes of Milan,' by Paulus Jovius (Paris, 1549) . ”
