I read an article on Encyclopedia Iranica(http://www.iranicaonline.org/articles/iran-viii2-classical-persian-literature) with an eye to see how this latest scholarly encyclopedia "canonize" authors/works. There are 80+ names of people who have written works in Persian offered - though for some their prime fame is in historiography (Bayhaqi), theology/sufism (Gazali) or philosophy (Avicenna)
This name list being that long, I seek to look at it through another entry on:
