Well, I definitely think it would help in creating a renaissance-like culture to know what technologies were available at that time, what buildings were in a typical city, what the population of that typical city was, and what were some normal cultural practices.
In my mind a culture like you are describing has travel primarily depending on horses or a similar animal, and fine horses are associated with upper military ranks and nobility. Structurally a community has a city at the center, located on either a water or land trade route. Further out surrounding the community would be lots of farms from which food was hauled in to feed the city dwellers. These farms might be grouped around either a nobleman's estate or a village controlled by a mayor.
The central community community is ruled by a hereditary leader because elections weren't that common yet. This leader probably had a religious title as well as being the head of the military either officially or unofficially. Working for this leader is a court of officials such as a treasurer, a secretary of state, advisers, judges, generals, noblemen in charge of outlying forts/castles which defend the perimeter of the country, and all the people who see to the food, clothing, and maintenance of the court and its facilities.
Militarily the invention of the recurved bow and possibly crossbows have negated the use of full plate armor although mid-weight armor like chain mail or breastplates are still worn for their benefit in melee combat. The army's major weapons are troops of cavalry and archers, but footmen are cheaper and thus there are many more of them.
Technologically, blacksmithing and glassworking exist, as do intentional breeding of animals to get offspring with desired traits and basic chemistry to create things like cement and pigments. But pretty much everything is still created by hand, there are no assembly lines or factories or anything more automated than a potter's wheel, lathe, or loom. Alas, except for public bath houses and palaces there is a general lack of hot water other than that boiled by the cauldron-ful. Understood mathematics probably includes trigonometry but not calculus. Formal universities either don't exist or are just getting started as academies sponsored by the government, a religious organization, and/or a society of noblemen and/or wealthy merchants.
There may be some social tension between the rising middle class and the hereditary upper class. Slavery might be formally regulated or might have been outlawed as the source of too many crimes and other problems. There might be an apprenticeship and guild system. The might be monasteries or abbeys. There is probably a central religious leader, who might directly serve the political leader or might be trying to be independent of the political leader. Circuses, faires, plays, musicians, tumblers and acrobats, fights (between animals or humans) dances, masquerades, feasts, and religious ceremonies account for most entertainment. Printing presses have probably been invented but movable type has not so book are still expensive.
Now, you might want to add magic into all that. Magic would make some things cheaper and others more expensive. Magic might enable some otherwise anachronistic things: sophisticated plumbing and heating/cooling of buildings, health care, "genetic engineering" of animals, "plastic surgery", possibly flying vehicles or mounts might speed travel, long-distance communication might be faster and more reliable, and magic might cause widespread small improvements to farming, mining, engineering, architecture, and all sorts of crafts.
