My main source about Decembrio is Mario Borsa, "Pier Candido Decembri e l'umanesimo in Lombardia" (Archivio Storico Lombardo, ser. 2, vol. X (1893) pp. 5-75 and pp. 358-441).
Borsa notes concerning Decembrio's Greek translations that he had a mediocre knowledge of Greek. His translation of the Republic took three years, beginning in 1438. First book V, finished in 1439 and sent to the Duke of Gloucester (and copied for others as well), then I, II, X and VI. Finally the rest was finished by 1440. Various humanists, Leonello d'Este, and King Giovanni II di Castiglia (John II of Castille), requested copies of each book as soon as each were finished. In 1441, Filippo Maria Visconti's orator Scaramuccio Balbo went to England to deliver a complete copy to the Duke of Gloucester.
Guarino judged the work to be a pure recreation of the Uberto and Chrysoloras version (of which some people had corrupt copies).
In any case, it is clear it was widely read and appreciated across Europe.
Duke of Gloucester .... born 1391, died Feb. 23, 1447, London, England ... that's interesting, cause he was nearly the same age and died in the same year as Filippo Maria.
.. really interesting ...

Regent of England since 1422 ... married to a very highstanding woman with some extraordinary scandals just around 1424, which is the time, when the French poet Cartier wrote his "cruel-beauty" poem ... forming the influential literary archetype of the unsatisfied lover ...
Cartier was not only poet, but also diplomat and it's likely, that he just had intensive contact to Filippo Maria Visconti just around this year of the poem, which also prepared likely the content of the Michelino-deck in 1425, that is the "oldest Tarot cards".
The major theme of this deck is Daphne, another "cruel woman", although antique and so a little older than the cruel beauty of Cartier.
Well, poet's naturally take themes, which somehow are in the air, and the air is formed from the general themes of the relevant "current moment" and the waves, that Jaqueline or Jacoba caused just in 1424 might habe been big enough to be a general theme, which was talked about at the courts. Cartier as active diplomat naturally knew about internal matters in this case.
Jaqueline - from Bavarian descendane - was married to a French Dauphin from 1415 - 1417, just on the way to become a French like Isabeau of Bavaria, wife of the long reigning Charles VI. the crazy. But the Dauphin died ... probably poisoned - first scandal around the young girl, which was now a 16-year-old widow.
Two monthes later her father died, and the result were serious difficulties between Jaqueline as correct heiress and her uncle. As a protector for her interests she married the 15 years old John IV, Duke of Brabant (Atrecht June 11, 1403 – April 17, 1427, Brussels), in the following year 1418.
Something was unlucky in this marriage and she left her husband in 1420, which resulted in an annulation of the marriage by the Avignon Pope Benedict XIII, who then was already abdicted by the council of Constance, but failed to be interested in the abdiction (second scandal).
Jaqueline went to England. As a new protector for Jaqueline then Humphrey, Duke of Gloucester, was found in England. The current English king opposed the marriage, but punctually this difficulty was solved, when the king died in 1422, leaving a just born heir as new king of England. "The death was unespected" - ... I don't find a reason, why, in the moment, but usually at such opportunities was talked of poison.
"It was only after the unexpected death of Henry V that Jacoba and Humphrey married. However, as not all rules were observed, this was in haste so that the actual date of their marriage, in October 1422, is unknown. She had hoped that Humphrey would restore her to her counties but, being regent in England, he was occupied with affairs of state."
Now Jaqueline "only nearly" was Queen of England, the regent's wife. ... somehow a third scandal.
Then the "situation changed as, on 6 January 1425, her uncle John of Bavaria died, the victim of poisoning." (the 4th scandal)
... and this just after (or are the dates wrong ?)
"At the end of 1424 Humphrey, with an army, moved to The Netherlands but was soon embroiled in politics between England and France as well as between the opposing Burgundians and Armagnacs. Soon Humphrey began to distance himself from her cause. The army in order to press their claim to Jacqueline's lands, where she was now opposed by her former husband, John of Brabant. In 1425 Humphrey deserted his wife, who found herself obliged to submit to her cousin, Philip III, Duke of Burgundy, after being besieged in the city of Mons in Hainault. Jacqueline was placed under house arrest in the chateau of Ghent."
... well, Cartier in 1424 couldn't look in the future, Tarot cards didn't exist ...
, but from his perspective in 1424 (Cartier was a man who worked for the Dauphin of France, the later Charles VII, and Charles VIII was naturally against England) an English "nearly a queen" was a foe and a poem about a "cruel beauty" ... well, that should have aimed at Jacqueline.
Did the scandals stop? No.
"At the end of 1425 Humphrey sent a fleet of twenty-four ships containing an army of 2,000 men under command of Lord FitzWalter. However, the cities in Zeeland were not prepared to assist and Jacoba had no army to come to their assistance. In the meantime, Philippe, Duke of Burgundy, had been prepared and, on 13 January 1426, started his attack on the main force. The English forces were annihilated and only the knights were not killed as they would secure a ransom. This victory placed Zeeland securely into Philippe's hands. On 27 February 1426 Pope Martin V decreed that Jacoba was still the wife of Jan IV, Duke of Brabant, and this released Humphrey from his obligations to come to her aid."
... well the marriage to Humphrey was divorced then (next scandal), and quasi Jacqueline was remarried again.
Jacqueline escaped of the chateaux, and, very practically, in 1427 husband Nr. 2 died, rather young (scandal ?).
Jacqueline fought against the duke of Burgund, had to make peace, married a 4th time in 1434, but died early 1436 (more in the wikipedia-article; she'd really an adventurous life).
Humphrey himself was released from the boundary of marriage and married Eleanor Cobham. And from this wife we hear:
"In 1441 three priests, Roger Bolingbroke, Eleanor's secretary; John Hunne, her chaplain; and Thomas Southwell were executed for conspiring to kill the king by witchcraft. Eleanor was tried on the same charges and admitted five of the twenty-eight counts. The authorities sentenced her to do public penance in London, divorced her from Humphrey and imprisoned her for life. She was exiled in the Isle of Man." (died ca. 1452 - 1454)
http://en.wikipedia.org/wiki/Eleanor_Cobham
So Humphrey had two scandalous women around him, beside that he's called a great humanist, which explains his interest in Platon ... but again, we find, that just this year 1441 seems to be crucial for him.
I've to think about that.
