One early printed portolan was written by Bartolommeo dalli Sonetti
(for sonnet; his real name was Bartolommeo Zamberti) about 1485.
The text, also closely related to the Liber Insularium written by Buondelmonte, has been put into short rhymes. The text
is illustrated with printed maps, which have an advantage over
manuscript maps because of the ease, rapidity and accuracy with
which they can be duplicated. The disadvantage is the lack of
detail that could be put on the woodblock used for printing. Woodcut
maps could not serve the needs of navigators nearly as well as
portolan charts.
