The mishna teaches: Rabbi Shimon ben Elazar says: If one finds any anpurya vessels he is not obligated to proclaim his find. The Gemara asks: What are anpurya vessels? Rav Yehuda says that Shmuel says: They are new vessels, as the eye of its purchaser has not yet sufficiently seen them to be able to recognize them. The Gemara asks: What are the circumstances? If there is a distinguishing mark on the vessels, when the eye of its purchaser has not yet sufficiently seen them, what of it?
The Mishnah uses the term as ἐμπορία emporia or Merchandise. New items that aren't familiar looking, and the owner hasn't gotten used to how they look. This is because sometimes lost items are returned just from recognizing them, for example to a scholar who doesn't lie. These items that are known that their owner's haven't gotten used to how they look aren't obligated to be announced.
We explore the emporia or marketplaces of antiquity with special reference to commerce in Roman Palestine.
