Then there are the adjectives formed from first names, or which relate to people known primarily by their first name: Mosaic (Mosaic law) Pauline (the Pauline epistles) Petrine (the Petrine era in Russia) Johannine (the Johannine doctrine of the Logos) Elizabethan Victorian Jacobean and many more.
I just listed 'phildickian' for Phil K. Dick, if you want to add it. Great list, by the way. I started one of my own before I found yours. I'm going to delete mine.
I'm taking cues from the website I posted below and wikipedia's list of eponymous adjectives.
The article posted mentions a certain "Literary League's Language Label Committee," which apparently makes authoritative decisions on the forms used for the adjectives, but I can't seem to find any more info about it.
Then there is the vexing case of Fabian, which could be an adjective related to a certain procrastinating Roman general, or a noun representing a certain former teen idol, for whom the relevant adjective would presumably have to be Fabianesque.
