Matthew Poole and continuators on Acts 19:24

24 For a certain man named Demetrius, a silver-smith, which made silver shrines for Diana, brought no small gain unto the craftsmen.

These shrines were only, either 1. Pourtraits of the Temple of Diana, in which was graven, or (by any other Art) represented that famous Structure which was afterwards burnt by Erastrotus: Or 2dly, They were Medals in which their Idol Diana was expressed according to her Image, spoken of, ver. 35. And they are called here, Temples, or Shrines, because they did resemble and represent that Shrine or Temple. And these the superstitious people carried home to their houses and friends; not only to evidence what a pilgrimage they had performed, but to incite the more their devotions towards this Idol.
