A silversmith - The word used here denotes "one who works in silver" in any way, either in making money, in stamping silver, or in forming utensils from it. It is probable that the employment of this man was confined to the business here specified, that of making shrines, as his complaint Acts . Acts 19:26-27 implied that destroying this would be sufficient to throw them out of all employment. Silver shrines ναοὺς naous. Temples. The word "shrine" properly means "a case, small chest, or box"; particularly applied to a box in which sacred things are deposited. Hence, we hear of the shrines for relics (Webster). The word "shrines" here denotes "small portable temples, or edifices," made of silver, so as to represent the temple of Diana, and probably containing a silver image of the goddess. Such shrines would be purchased by devotees and by worshippers of the goddess, and by strangers, who would be desirous of possessing a representation of one of the seven wonders of the world. See the notes on Acts 19:27. The great number of persons that came to Ephesus for her worship would constitute an ample sale for productions of this kind, and make the manufacture a profitable employment. It is well known that pagans everywhere are accustomed to carry with them small images, or representations of their gods, as an amulet or charm. The Romans had such images in all their houses, called penates, or household gods. A similar thing is mentioned as early as the time of Laban Genesis 31:19, whose images Rachel had stolen and taken with her. Compare Judges 17:5, "The man Micah had an house of gods"; 1-Samuel 19:13; Hosea 3:4. These images were usually enclosed in a box, case, or chest, made of wood, iron, or silver; and probably, as here, usually made to resemble the temple where the idol was worshipped.
Diana - This was a celebrated goddess of the pagan, and one of the twelve superior deities. In the heavens she was Luna, or Meui (the moon); on earth, Diana; and in hell, Hecate. She was sometimes represented with a crescent on her head, a bow in her hand, and dressed in a hunting habit; at other times with a triple face, and with instruments of torture. She was commonly regarded as the goddess of hunting. She was also worshipped under the various names of Lucina, Proserpine, Trivia, etc. She was also represented with a great number of breasts, to denote her as being the fountain of blessings, or as distributing her benefits to each in their proper station. She was worshipped in Egypt, Athens, Cilicia, and among pagan nations generally; but the most celebrated place of her worship was Ephesus, a city especially dedicated to her.
Unto the craftsmen - To the laborers employed under Demetrius in the manufacture of shrines.

Silver shrines for Diana - It is generally known that the temple of Diana at Ephesus was deemed one of the seven wonders of the world, and was a most superb building. It appears that the silver shrines mentioned here were small portable representations of this temple, which were bought by strangers as matters of curiosity, and probably of devotion. If we can suppose them to have been exact models of this famous temple, representing the whole exterior of its magnificent workmanship, which is possible, they would be held in high estimation, and probably become a sort of substitute for the temple itself, to worshippers of this goddess who lived in distant parts of Greece. The temple of Diana was raised at the expense of all Asia Minor, and yet was two hundred and twenty years in building, before it was brought to its sum of perfection. It was in length 425 feet, by 220 in breadth; and was beautified by 127 columns, which were made at the expense of so many kings; and was adorned with the most beautiful statues. To procure himself an everlasting fame, Erostratus burned it to the ground the same night on which Alexander the Great was born. It is reported that Alexander offered to make it as magnificent as it was before, provided he might put his name on the front; but this was refused. It was afterwards rebuilt and adorned, but Nero plundered it of all its riches. This grand building remains almost entire to the present day, and is now turned into a Turkish mosque. See an account of it in Montfaucon, Antiq. Expliq. vol. ii., with a beautiful drawing on plate vi., No. 20. See also Stuart's Athens. There were also pieces of silver struck with a representation of the temple of Minerva on one side: many coins occur in the reigns of the first Roman emperors, where temples, with idols in the porch, appear on the reverse; and several may be seen in Muselius, in the reigns of Trajan, Adrian, Antoninus Pius, etc. A beautiful representation of the temple of Diana at Ephesus may be seen on a medal engraved by Montfaucon, in his Antiq. Expliq. Suppl. vol. ii. plate 33. It has eight Doric columns in front, which Pliny says were sixty feet in length. In the entrance, the figure of Diana is represented with a sort of tower upon her head; her arms are supported by two staves; at her feet are represented two stags with their backs towards each other. The sun is represented on the right side of her head, and the moon as a crescent on the left. On each side and at the bottom of this temple are the words, πρωτων Ασιας Εφεσιων. Some think that the medals here referred to are the same that are meant by the silver shrines made by Demetrius and his craftsmen. See the note on Acts 19:27.
Brought no small gain - There were many made, many sold, and probably at considerable prices.

For a certain [man] named Demetrius, a silversmith, which made silver (l) shrines for Diana, brought no small gain unto the craftsmen;
(l) These were special counterfeit temples with Diana's picture in them, which those who worshipped her bought.

For a certain man, named Demetrius, a silversmith,.... Who worked in silver, not in coining silver money, but in making silver vessels, in melting silver, and casting it into moulds, and forming it into different shapes; and particularly,
which made silver shrines for Diana; who Diana was; see Gill on Acts 19:27, these were not coins or medals of silver, struck by Demetrius, with the figure of the temple of Diana on them, nor images of Diana, as the Ethiopic version reads; but they were chaplets, or little temples made of silver, in imitation of the temple of Diana at Ephesus, with her image included in it; the words may be rendered, "silver temples": in some manuscripts it is added, "like little chests": which being sold to the people,
brought no small gain to the craftsmen: who were of the same trade with him; masters of the same business, who employed others under them, as appears by what follows.

silver shrines for--"of"
Diana--small models of the Ephesian temple and of the shrine or chapel of the goddess, or of the shrine and statue alone, which were purchased by visitors as memorials of what they had seen, and were carried about and deposited in houses as a charm. (The models of the chapel of our Lady of Loretto, and such like, which the Church of Rome systematically encourages, are such a palpable imitation of this heathen practice that it is no wonder it should be regarded by impartial judges as Christianity paganized).
gain to the craftsmen--the master-artificers.

Silver shrines - Silver models of that famous temple, which were bought not only by the citizens, but by strangers from all parts. The artificers - The other silversmiths.
