Other innovations

Although perhaps not as prolific as other areas of Greece in regards to technological innovations, there are some inventions that may have originated in Macedonia aside from siege engines and artillery. The rotary-operated olive press for producing olive oil may have been invented in ancient Macedonia or another part of Greece, or even as far east as the Levant or Anatolia. Mold-pressed glass first appeared in Macedonia in the 4th century BC (although it could have simultaneously existed in the Achaemenid Empire); the first known clear, translucent glass pieces of the Greek world have been discovered in Macedonia and Rhodes and date to the second half of the 4th century BC. Greek technical and scientific literature began with Classical Athens in the 5th century BC, while the major production centers for technical innovation and texts during the Hellenistic period were Alexandria, Rhodes, and Pergamon.
