Marcus Tullius Cicero (106-65 BCE) was a politician, orator and speechwriter who had a very elaborate writing style. His parents were very wealthy and like most well-to-do kids back then, he was sent to Greece where he dormed in Athens.

He learned to be a verbal artist--the overstatements in sarcastic vein and all the tricks and devices of rhetorical discipline.

When you look at Ciceronian influences on the language back then and compare that to the Roman language that existed 200 years later you will see differences.
For instance, Cicero would pronounce the word "agricolae" ( which means "farmers" in English) with the -ae sounding like "ay".
200 years or so later when the Roman Catholic church took command of the language the -ae was pronounced as "I".
This is an example of the Ciceronian declension.
So when something is described as being of the "Ciceronian Declension" then that something is being described as being eloquent.
