I was reading Nietzsche's
Human, All Too Human and found this struck a cord with me when considering CAS, he did focus on the bygone (fantasy) days.
148: How poets ease life. Poets, insofar as they too wish to ease men's lives, either avert their glance from the arduous present, or else help the present acquire new colors by making a light shine in from the past. To be able to do this, they themselves must in some respects be creatures facing backwards, so that they can be used as bridges to quite distant times and ideas, to religions and cultures dying out or dead. Actually, they are always and necessarily epigones. Of course, some unfavorable things can be said about their ways of easing life: they soothe and heal only temporarily, only for the moment; they even prevent men from working on a true improvement of their conditions, by suspending and, like a palliative, relieving the very passion of the dissatisfied, who are impelled to act.
