‘It is always the unreadable that occurs.’ –Oscar Wilde
Damnatio memoriae is the Latin phrase literally meaning “condemnation of memory” in the sense of a judgment that a person must not be remembered. […] The intent was to erase someone from history, a task somewhat easier in ancient times, when documentation was much sparser. […]
Any truly effective damnatio memoriae would not be noticeable to later historians, since, by definition, it would entail the complete and total erasure of the individual in question from the historical record.
