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] This city, as appears from its coins – which bear the epigraph Δημος or Ιερα Συνκλητος Δοκιμεων Μακεδονεν – where the inhabitants are called Macedonians, may have been founded by Antigonos Dokimos.
[8] Docimian marble was highly admired and valued for its unique colors and fine grained quality by ancient people such as the Romans.
These colours which streaked the white marble, taken from the city's holy mountain, were attributed to the drops of blood from the dying god Attis.
