There’s not much mystery about the main graphics here – it’s the Magna Carta, usually assigned to 1215. The Magna Carta is widely believed to be some great document enshrining the democratic rights of ordinary people. In reality, it was a typical political deal — in the words of Dan Jones in The Telegraph:
Politicians today love to invoke Magna Carta as a bulwark for the rights of the ordinary man. But it would be more accurate to say that Magna Carta’s clauses variously offered special legal protection for the Catholic Church and the aristocracy, advocated tax breaks for the wealthiest, freed the City of London from regulatory oversight, promised total freedom of immigration and placed the burden of infrastructure maintenance on local communities instead of government. Any party that stood on a platform that was true to the spirit of Magna Carta today would be massacred at the polls.
The image of a magnifying glass isn’t a pun on “magni-carta”, but a reference to Roger Bacon (1220 to 1292), who is believed to be the originator (or at least introducer) of the use of the magnifying glass for scientific purposes, probably around 1250.
The other noticeable feature of the disk is the profusion of rabbits. These refer to the famous puzzle posed by Leonardo Bonacci, also known as Fibonacci, in his book Liber Abaci (1202). Fibonacci considers the growth of rabbits, and assumes that a pair of rabbits, one male and one female, mate at the age of one month so that at the end of the second month a female can produce another pair of one male and one female rabbit. The puzzle was: how many pairs will there be after one year? The Fibonacci sequence — 1 1 2 3 5 8 13 21 etc. — is named after him.
Decoding the symbols using the Utopian Alphabet key, and flipping the lines vertically or horizontally, as necessary, gives:

Which, at a rough guess, gives these fragments of ‘poetry’:
