In no particular order:

Book of the New Sun series by Gene Wolfe. (Highly recommended)

A Fire Upon the Deep (Either you like the Tines or the Skroderiders)

Tlön, Uqbar, Orbis Tertius by Jorge Borges (Is reality imbued with our ideas?)

Conan the Barbarian by Robert E. Howard (Not unlike "the Greeks" of modern fic)

John Carter of Mars by Edgar Rice Burroughs (perhaps the first true modern fic)

Understand by Ted Chiang (Most of his short stories are good, or provoking)

Xeethra and the Zothique Cycle by Clark Ashton Smith

The Dying Earth by Jack Vance
