Maybe kind of a strange question, but I remembered recently that as the Catholic church grew in power in Italy, they began censoring the nude works left behind by the Romans (example, putting leaves on genitalia). I also know that Vatican City has it's own museum and it contains Roman works. Over time, what was the Church's opinion on Ancient Rome, and did it censor anything else like the allusions to paganism? When did it come to admire the Empire and Republic like many people did in the past and continue to today? Or did it ever condemn it? You would think that as someone who grew up Catholic I would know this hahaha but I'm curious.
First we have to think about what we consider what the start of the Catholic Church is. That is a whole can of worms that we could talk about but that would just be paragraphs of text that don't really have anything to do with what you are asking. So I am going to just talk about general trends that happened over time in the western orthodox tradition that eventually became the Catholic Church.
Very early Christians did not like the roman empire but there were some early converts that pushed to make changes to make it more palatable for Roman converts. The most prominent example of this for your questions is that over time Christians put less and less of the blame of Jesus's death on the Romans and this had the unfortunate side effect of having more and more blame placed unto the Jews. This snowballed so that even very soon after the collapse of the Western Roman Empire there was still a lot of pro-roman sentiment in the Catholic Church and all prior acts of brutality inflicted on Christians are hand waved as having their origins in the pagan beliefs of Rome at the time.
So with your question of censorship, this is very hard for some people to understand, but despite things disappearing over time that was uncomfortable to the Catholic Church, this wasn't really due to some system of censorship. The Catholic Church was the only organization with the resources and/or desire to keep making and reprinting history in Western Europe. So there was general trend for scribes to edit out or change things they found uncomfortable and because these scribes were usually monks or other people that were part of the church hierarchy it usually aligned with the Catholic Church.
Now surprisingly Greek and Roman history was relatively spared from this depaganization due to the greater respect the Catholic Church had for the Greek and Roman cultures, there was a greater sense that these Greeks and Romans were so amazing that they should leave their works as they are, "warts and all". This is one of the reasons we know so much more about Greek and Roman gods and religious practices then we do about a lot of other religions that were replaced with early Christianity.
