It is well known that "bad money drives out good" and apparently this law was known to Aristophanes, to the Mamluk Al Maqrizi, ..., and finally to Gresham; hence the Gresham's law concerning good and bad money.
I do not plan to become known through a similar law (e.g., Go:bekli kanunu) but I will assert that bad historiography drives out good. As an example, one may compare what is believed to be known about Zalogo and what is, as a rule, not known about the Husainids and Mustapha Khaznadar.
