city became a Macedonian colony. Polybius tells how Philip laid siege to the city, first building three camps and then joining them up with lines of circumvallation. Though initially the city offered determined resistance the citizens surrendered when a section of the wall that Philip had mined collapsed. It was attacked by the consul Titus Quinctius Flamininus, previous to the Battle of Cynoscephalae, 197 BCE, but without success. Following Philip's defeat by the Roman Republic in the Second Macedonian War, in 189 BCE Phthiotic Thebes again became capital of the restored Phthiotic Achaean League. The name of Philippopolis was gradually dropped, though both names are used by Livy in narrating the transactions of the year 185 BCE. It continued to exist under the name of Thebes in the time of the Roman Empire, and is mentioned by Hierocles in the sixth century. Under the Roman Empire, the city was moved from the inland site of the old Phthiotic Thebes back to Pyrasos. The old site was not abandoned, but for the remainder of the city's existence, its centre lay at the site of Pyrasos, where the harbour was also located. In Late Antiquity, it became part of the province of Thessaly, of which it was the third-most important city and main harbour. The city's prosperity from the 4th through the 6th centuries is attested by the number of its Early Christian monuments, but was brought to an end in a great fire in the late 7th century that destroyed the city. The city was rebuilt and apparently continued to be of some note in the early Byzantine period—its bishop is last mentioned in the 8th/9th century—but never recovered and was eventually eclipsed by the nearby port city of Halmyros. Archaeological remains According to the Oxford Dictionary of Byzantium, the site "is best known because of the many churches excavated there (nine basilicas have been found)". These include: Basilica A, a three-aisled basilica from the late 5th/early 6th century, dedicated to Saint Demetrius, which served as the cathedral church. Basilica B, or "Elpidios Basilica", also dating roughly to the late 5th/early 6th century. Basilica C, also known "Church of the archiereus Peter" based on a mid-6th century inscription, although it dates to the late 4th/early 5th century. It features "elaborate floor mosaics and is part of a vast ecclesiastical complex". Basilica D, a 7th-century cemetery church outside the city walls. The
