Giustiniani wrote and delivered a funeral oration for Admiral
Carlo Zeno in 1418. In 1420, while his brother Marco was serving as
podestà of
Bergamo, he wrote a prologue to its laws,
Proemium in leges et statuta Pergami. He translated
Plutarch's lives of
Cimon,
Lucullus and
Phocion from Greek into Latin. His surviving correspondence was described by Aldo Oberdorfer as "among the most sincere and spontaneous of the age". His treatise
Regulae artificialis memoriae ('Rules on the Art of Memory'), addressed to his son, elaborates a complicated system of mnemonic devices. Giustiniani wrote secular and religious poetry. In formal Italian with
Venetian characteristics, he wrote
laude,
strambotti and both short and long love songs. He also wrote music and was known in his own day for his singing to the accompaniment of the
lute. Musical settings for some of the
laude survive, but not for the
strambotti.The longer love poems are collected in his
Canzoniere, the shorter in
Il fiore delle … canzonette del … Lunardo Iustiniano, published at Venice around 1472. At least four of the
canzonette are considered spurious, but all thirty have
polyphonic musical settings. Many letters to and from Giustiniani survive. His correspondents include Ciriaco d'Ancona, Guarino Veronese,
Francesco Barbaro,
Benedetto Bursa,
Federico Cornaro,
Francesco Filelfo,
Andrea Giuliani,
Barbone Morosini,
Lauro Quirini,
Palla Strozzi,
Pietro Tommasi and
Ambrogio Traversari. == Notes ==
