This category does not require a rating on the project's quality scale.
Few articles actually belong directly in this category. "European mythology" does not exist as such, except as a geographic grouping of other mythologies (Greek, Irish, Norse and so on). Articles already categorized as "Irish mythology" are therefore ipso facto in a sub-category ("Celtic mythology") of this category. There's no useful benefit to duplication in this case.
