O ziołach i o mocy jich (“About herbs and their power”) was the first Polish encyclopedia of natural history and medicine. It was published in 1534 by the well-known Cracow printer Florian Ungler. Selected fragment talks about the belief that birds body parts could be used to cure various diseases. Both Algo FY and Alegreya (used for body text) refer to typography used in the early 16th century books. Algo FY combines both roman and blackletter construction in a very modern and unique way.
O ziołach i o mocy jich is part of the New Dimension of Old Typography series which consists of 10 redesigns of Polish books from the sixteenth to the nineteenth century. The designs were produced as a part of a doctoral dissertation at the Akademia Sztuk Pięknych w Gdańsku (Academy of Fine Arts in Gdansk, Poland).
