Thessalonica in the Bible Encyclopedia - ISBE

thes-a-lo-ni'-ka (Thessalonike, ethnic Thessalonikeus): 1. Position and Name: One of the chief towns of Macedonia from Hellenistic times down to the present day. It lies in 40 degrees 40 minutes North latitude, and 22 degrees 50 minutes East longitude, at the northernmost point of the Thermaic Gulf (Gulf of Salonica), a short distance to the East of the mouth of the Axius (Vardar). It is usually maintained that the earlier name of Thessalonica was Therma or Therme, a town mentioned both by Herodotus (vii.121 ff, 179 ff) and by Thucydides (i.61; ii.29), but that its chief importance dates from about 315 BC, when the Macedonian king Cassander, son of Antipater, enlarged and strengthened it by concentrating there the population of a number of neighboring towns and villages, and renamed it after his wife Thessalonica, daughter of Philip II and step-sister of Alexander the Great. This name, usually shortened since medieval times into Salonica or Saloniki, it has retained down to the present. Pliny, however, speaks of Therma as still existing side by side with Thessalonica (NH, iv.36), and it is possible that the latter was an altogether new foundation, which took from Therma a portion of its inhabitants and replaced it as the most important city on the Gulf. 2. History: Thessalonica rapidly became populous and wealthy. In the war between Perseus and the Romans it appears as the headquarters of the Macedonian navy (Livy xliv. 10) and when, after the battle of Pydna (168 BC), the Romans divided the conquered territory into four districts, it became the capital of the second of these (Livy xlv.29), while later, after the organization of the single Roman province of Macedonia in 146 BC, it was the seat of the governor and thus practically the capital of the whole province. In 58 BC Cicero spent the greater part of his exile there, at the house of the quaestor Plancius (Pro Plancio 41, 99; Epistle Ad Att, iii.8-21). In the civil war between Caesar and Pompey, Thessalonica took the senatorial side and formed one of Pompey's chief bases (49-48 BC), but in the final struggle of the republic, six years later, it proved loyal to Antony and Octavian, and was rewarded by receiving the status and privileges of a "free city" (Pliny, NH, iv.36). Strabo, writing in the reign of Augustus, speaks of it as the most populous town in Macedonia and the metropolis of the province...
