All kinds. In the Western world there are 2,000 year old myths that persist to this day and are part of mainstream cultural knowledge. People think you’re crazy if you don’t know them.
True, but we have been a literate society throughout that timespan, and the institution that was responsible for maintaining the knowledge of such myths, the Church, was often the only source of literacy around.
A lot of the ancient secular stuff was forgotten and had to be reconstructed later from written sources.
