Apollonia in Cyrenaica (modern Libya) was founded by Greek colonists and became a significant commercial centre in the southern Mediterranean, which continued right until the East Roman (Byzantine) Empire era. It served as the harbor of Cyrene, 20 km (12 mi) to the southwest. An earthquake damaged the city in 365, but it survived, although many ancient buildings were destroyed. Nevertheless, Apollonia became more important than it had ever been, because in the fifth century, the interior was abandoned to the Libyan Laguatan nomads. The port remained one of the last bases of Byzantine troops during the Muslim invasions. There were several new building projects, like the eastern, central, and western basilicas. The town, refortified during the Ananeosis ("renewal") but in the end conquered by the Arabs, was abandoned in the Middle Ages. Apollonia became autonomous from Cyrene at latest by the time the area came within the power of Rome, when it was one of the five cities of the Libyan Pentapolis, growing in power until, in the 6th century A.D., it became the capital of the Roman province of Libya Superior or Libya Pentapolitana. The city became known as Sozusa, which explains the modern name of Marsa Susa or Susa, which grew up long after the cessation of urban life in the ancient city after the Arab invasion of AD 643. The early foundation levels of the city of Apollonia are below sea level due to submergence in earthquakes, while the upper strata of the later Byzantine Christian periods are several meters above sea level, built on the accumulated deposits of previous periods. The Palace was last used as the Byzantine Duke's Palace and contains over 100 rooms. The previous use was as a Roman military commander's house. The well-preserved Greek theater stands facing the sea outside the old city walls. The cavea has 28 seat levels. Apollonia was founded as the port of Cyrene. In case of an emergency, like the Arab invasions in the late 600s, the walls had to be defended. The walls of Apollonia, therefore, do not date back to the oldest stage of occupation, but were built in the Hellenistic Age. They are very well preserved, especially in the southeast. The Palace of Apollonia Gate going to the central court of the palace. Apollonia was made capital of a newly created province, Libya Superior, by the emperor Diocletian (r.284-305). It was renamed Sosouza ("savioress"), probably after a goddess who was venerated here (Isis?). The military leader of the region, the dux, built his palace in the city, and rebuilt the original wall from the third century BCE, which was next to it. The photo above shows one of the gates that gave access to the central court. As you can see, a cross was cut into the stone over this door: a memory of the Christianisation of the Roman empire during the reign of Constantine the Great (r.306-337) and his son Constantius II (r.337-361). The palace once had two stories, but only the rooms on the ground floor - where the governor received his guests - remain. There were two large villas near this monument, which were probably used as an annex to the palace. Apollonia became especially important in the fifth century, when the interior was abandoned to the Laguatan nomads (Synesius of Cyrene describes these disastrous years in his Catastasis). The port remained one of the last bases of the Byzantine troops and the palace of the dux must have been one of the most important military buildings in the Cyrenaica. According to Procopius, the Byzantine Empress Theodora spent several years in the palace of Apollonia, as mistress of a governor named Hecebolus. Later, she married Justinian (527-565) and became one of the most powerful women from Antiquity. Reconstruction of the port of Apollonia (Livius) The port of Apollonia was built around two or three natural harbors, which have disappeared beneath the waves in 365 CE, when a giant tidal wave destroyed the coast of northern Africa. It seems that the inner harbor - which was surrounded by quays and store houses - was used for warships, and the outer harbor for merchant ships. In the eastern part were a large mole and a lighthouse. This mole and the outer harbor were built by the Romans; the inner harbor appears to be Greek. In 1987, a small ship (thirteen meters long) was discovered; the remains are now in the museum of Sousa. Port facilities: Apollonia was an important port for commerce in North Africa. The Bathhouse Apollonia, bathhouse and port. The Bathhouse was built during the reign of the emperor Hadrian (117-138). Probably, the court that is the core of the bathhouse is the peristyle of an older house: many Greek houses from the Hellenistic age were built around a garden-court (cf. the Villa of the Four Seasons Mosaic in Ptolemais and the Villa of Jason Magnus in Cyrene). Today, you can still see the courtyard, which was once surrounded with Corinthian columns, and must have been used by people doing their athletic exercises (palaestra). Also visible are the real baths, which were still in use in the fourth century. The original entrance must have been to the north, where the main road of Apollonia used to be until, in 365, a large tidal wave destroyed much of the city. After that, the Baths were abandoned; it seems that people were living in the old monument. Military and Civil Administration Egypt was formed into a separate diocese in about 381. According to the Notitia Dignitatum, which for the Eastern part of the Empire dates to ca. 401, the diocese came under a vicarius of the praetorian prefecture of the East, with the title of praefectus augustalis, and included six provinces: \tAegyptus (western Nile delta), originally established in the early 4th century as Aegyptus Iovia, under a praeses \tAugustamnica (eastern Nile delta), originally established in the early 4th century as Aegyptus Herculia, under a corrector. \tArcadia (central), established ca. 397 and having previously briefly listed in the 320s as Aegyptus Mercuria, under a praeses \tThebais (southern), under a praeses \tLibya Inferior or Libya Sicca, under a praeses \tLibya Superior or Pentapolis, under a praeses Parallel to the civil administration, the Roman army in Egypt had been placed under a single general and military governor styled dux (dux Aegypti et Thebaidos utrarumque Libyarum) in the Tetrarchy. Shortly after the creation of Egypt as a separate diocese (between 384 and 391), the post evolved into the comes limitis Aegypti, who was directly responsible for Lower Egypt, while the subordinate dux Thebaidis was in charge of Upper Egypt (Thebais). In the middle of the 5th century, however, the latter was also promoted to the rank of comes (comes Thebaici limitis). The two officers were responsible for the limitanei (border garrison) troops stationed in the province, while until the time of Anastasius I the comitatenses field army came under the command of the magister militum per Orientem, and the palatini (guards) under the two magistri militum praesentales in Constantinople. The comes limitis Aegypti enjoyed great power and influence in the diocese, rivalling that of the praefectus augustalis himself. From the 5th century, the comes is attested as exercising some civilian duties as well, and from 470 on, the offices of comes and praefectus augustalis were sometimes combined in a single person. This tendency to unite civil and military authority was formalised by Justinian I in his 539 reform of Egyptian administration. The diocese was effectively abolished, and regional ducates established, where the presiding dux et augustalis was placed above the combined civil and military authority: \tdux et augustalis Aegypti, controlling Aegyptus I and Aegyptus II \tdux et augustalis Thebaidis, controlling Thebais superior and Thebais inferior \tAugustamnica I and Augustamnica II were likewise probably — the relevant portion of the edict is defective — were placed under a single dux et augustalis \tin the two Libyan provinces, the civil governors were subordinated to the respective dux \tArcadia remained under its praeses, probably subordinated to the dux et augustalis Thebaidos, and a dux et augustalis Arcadiae does not appear until after the Persian occupation of 619–629.

From Megas Alexandros In 322 BC, the year after Alexander’s death, Ptolemy I who had established himself as ruler of Egypt conquered five Libyan cities. They are collectively known as the Pentapolis and include beside Cyrene, the cities of Apollonia, Ptolemais or Barca, Arsinoe or Taucheira (modern Tocra) and Euesperides or Berenice (near modern Benghazi). In those days, Cyrenaica was part of greater Egypt and often simply assimilated to Egypt itself. The region was very fertile and produced wheat and barley, as well as olive oil and wine; the orchards in turn were filled with fig and apple-trees; sheep and cattle roamed widely; and above all, this was the only place in the world where silphium grew, a natural medicine, a contraceptive and aphrodisiac. Apollonia was founded by Greek colonists as early as the 7th century BC and during the fourth century BC the harbor facilities were widely improved, sheltering the berths against the strong northern winds. On the west side a new inland port was constructed, protected by two towers while on the most eastern island a lighthouse was installed. It was only in the first century BC that Apollonia became a city in its own right. Not for long, however, since upon Ptolemy III’s death in 96 BC the entire Pentapolis, including Cyrene and Apollonia was bequeathed to the Romans who just moved a step closer to Egypt itself … Apollonia was part of The Diocese of Egypt which was a diocese of the later Roman Empire (from 395 the Eastern Roman Empire), incorporating the provinces of Egypt and Cyrenaica. Its capital was at Alexandria, and its governor had the unique title of praefectus augustalis ("Augustal Prefect", of the rank vir spectabilis; previously the governor of the imperial 'crown domain' province Egypt) instead of the ordinary vicarius. The diocese was initially part of the Diocese of the East, but in ca. 380, it became a separate entity, which lasted until its territories were finally overrun by the Muslim conquest of Egypt in the 640s. Today’s visitor to Apollonia will only find half of the antique city as the other half lies under water. Northern Africa has suffered badly from a devastating earthquake that occurred in 365 AD, causing the entire coastline to drop by four meters. The phenomena is clearly visible here in Apollonia where the old harbor is entirely drowned and the three off-shore islands is all that remains of the northern pier. This explains why the city doesn’t have the appeal of a harbor, and certainly not one to serve a city as important as Cyrene. Apparently shipwrecks from the fourth century BC have been located in the antique harbor where French archeologists were diving during my visit in 2010. I hate to think about what has happened since. Anyway, Apollonia’s remains are mainly Byzantine, with three Basilicas: the western Basilica with three naves; the central Basilica with five naves; and to the far end the eastern Basilica, the largest, from the 6th century with an exceptional Baptistery because it counts six steps instead of the normal three. My local guide tells me that in the Byzantine era the purpose of this Baptistery was not to baptize people in order to convert them but to receive forgiveness for their sins. One submersion would cleanse the believer from small sins, but for more serious offenses five or six submersions would be required. I never heard of this theory but it may be a logical explanation for the great number of baptisteries in these churches. Next to the central Basilica are the remains of a Roman Bath, whose lay-out, except for the entrance gate, is rather confusing. That is no surprise when you think how the Byzantines liked to re-model Roman buildings or re-use their stones elsewhere. Alongside the Byzantine city wall and approximately across from the Roman Baths, lies the Palace of the Dux, the Byzantine governor Hekobolius from the 6th century, i.e. the time when Apollonia was the capital of the Pentapolis. The palace itself has not much to offer but the story that goes with it is rather interesting. For nearly six years, this Hekobolius kept an extremely good looking mistress called Theodora. One day she happened to be dancing in Constantinople for Emperor Justinian who fell in love head over heels and married her soon after. This is how Empress Theodora arrived at the imperial court where she lived happily ever after … Well, this marriage lasted about twenty years and Theodora died before Justinian, on 28 June 548. There are more remains of Apollonia that have not yet been excavated, including the Acropolis at the far end of the site. Outside the city-wall lies the inevitable Roman theater (although built on an earlier Greek one) that now lies near the shoreline. According to an inscription found near the podium, it was built in 92 AD during the reign of Emperor Diocletian. This is the best preserved theater of the Cyrenaica in spite being used as a quarry by the Byzantines. A last glance over Apollonia makes me realize that the restored columns of the different Basilicas are the most notable features, but that is primarily because of their texture. All these columns are made of cipolin marble, imported from the island of Euboea before the coast of eastern Greece. Cipolin is the Italian name for onions and is used to describe this kind of marble which, like onion skins, appears in green-greyish streaks – a very appropriate name, I must say. Walking back along the coastline, my attention is drawn towards four large round pits carved in the rock. These pits were used to marinate fish in order to make the famous garum or fish paste, a delicacy for the Romans. How interesting!
