Docimium, Docimia or Docimeium (Greek: Δοκίμια and Δοκίμειον) was an ancient city of Phrygia, Asia Minor where there were famous marble quarries.[1] The exact site of Docimium was a matter of some dispute until recently; it is now fixed at the modern Turkish town İscehisar, in Afyonkarahisar Province.[2]
