How Thessalonica: The Roman Forum and the Arch of Galerius was found

Digging for a new law-court in the city centre struck the marble paving and cryptoporticus of the Roman agora; the project was abandoned and the square excavated, revealing the odeon, stoas, a mint and public baths. Two blocks away the four-way triumphal arch of Galerius carries reliefs of his Persian war.

What it is

A two-terraced marble-paved square about 150 by 100 m with double-storey stoas on three sides, a vaulted underground gallery (cryptoporticus) of shops, an odeon of about 400 seats, and bath buildings. The Arch of Galerius, of brick faced with sculpted marble panels, once spanned the Via Egnatia and led to the domed Rotunda, later a church.

Why it matters for the Bible

The forum is the agora of Acts 17:5, where a mob of 'loafers from the marketplace' dragged Jason before the politarchs (whose inscription has its own entry) crying that Paul's friends 'turned the world upside down' and claimed 'another king, Yeshua'. The excavated square, with its odeon and civic offices, is exactly that setting, though its visible marble is a 2nd-century rebuild. The Arch of Galerius, raised 250 years later by the emperor who launched the Great Persecution, shows the imperial claim to kingship against which the Thessalonian believers had been accused.

The Hebrew word: SHOOK

שׁוּק

שׁוּק is pronounced SHOOK and means street, market — the agora where the crowd was gathered against Paul (Strong's H7784).
