Sar’dis, a city of Asia Minor, and capital of Lydia, situated about two miles to the south of the river Hermus, just below the range of Tmolus, on a spur of which its acropolis was built. It was 50 miles northeast of Smyrna. It was the ancient residence of the kings of Lydia, among them Crœsus, proverbial for his immense wealth. Cyrus is said to have taken $600,000,000 worth of treasure from the city when he captured it, b.c. 548. Sardis was in very early times, both from the extremely fertile character of the neighboring region and from its convenient position, a commercial mart of importance. The art of dyeing wool is said to have been invented there. In the year 214 b.c. it was taken and sacked by the army of Antiochus the Great. Afterward it passed under the dominion of the kings of Pergamos. Its productive soil must always have continued a source of wealth; but its importance as a central mart appears to have diminished from the time of the invasion of Asia by Alexander. The massive temple of Cybele still bears witness in its fragmentary remains to the wealth and architectural skill of the people that raised it. On the north side of the acropolis, overlooking the valley of the Hermus, is a theatre near 400 feet in diameter, attached to a stadium of about 1000. There are still considerable remains of the ancient city at Sert-Kalessi. Travellers describe the appearance of the locality as that of complete solitude. The only passage in which it is mentioned in the Bible is Rev. 3:1-6.
