In the early
Byzantine period (4th to 6th centuries AD) Heraclea was an important episcopal centre. Some of its bishops have been noted in the acts of the Church Councils as
bishop Evagrius of Heraclea in the Acts of the
Sardica Council from 343 AD. A small and a great basilica, the bishop's residence, and a funerary basilica and the necropolis are some of the remains of this period. Three
naves in the Great Basilica are covered with
mosaics of very rich floral and figurative
iconography; these well preserved mosaics are often regarded as fine examples of the early
Christian art period. Other bishops from Heraclea are known between 4th and 6th century AD as bishop Quintilinus mentioned in the Acts of the
Second Council of Ephesus, from 449 AD. The city was sacked by
Ostrogoth/
Visigoth forces, commanded by
Theodoric the Great in 472 AD and, despite a large gift to him from the city's bishop, it was sacked again in 479 AD. It was restored in the late 5th and early 6th century. When an earthquake struck in 518 AD, the inhabitants of Heraclea gradually abandoned the city. Subsequently, at the eve of the 7th century, the
Dragovites, a
Slavic tribe pushed down from the north by the Avars, settled in the area. The last coin issue dates from ca. 585, which suggests that the city was finally captured by the Slavs. As result, in place of the deserted city theatre several huts were built.
Mosaics in the basilicas The so-called Small Basilica was discovered in excavations made before the outbreak of
World War II between 1936 and 1938. At first it was thought to be an ancient palace, but in the later research from 1960 to 1964, it became clear that it was an early Christian
basilica. There is a decorated floor mosaic laid in the technique of "
opus sectile" within the basilica and several rooms have been unearthed. The first room was used for baptizing, and the second room has a floor mosaic made in "
opus tessellatum" technique. After the creation of the complex Great Basilica, the function of these rooms was changed. By discovering the walls, architectonic plastic and floors were reconstructed electronically. The Great Basilica is a monumental building with a room of open porch colonnades, a room of
exonarthex, one of
narthex, two north annexes, and a room of three south annexes. The floors of these rooms have mosaics with geometric and floral designs. The mosaic in the narthex is of early
Byzantine art, a big composition at a size of . There are birds, trees, bushes, a red dog, which is a symbol of paradise, and animals beasts as a domain of the earth. This mosaic dates from the end of the 6th century. The Great Basilica is built on top of another pre-existing one and it is believed to have been built sometime between the 4th and 6th century. The Great Basilica's mosaic floor is depicted on the
reverse of the Macedonian 5000
denars banknote, issued in 1996. The Episcopacy Residence was excavated between 1970 and 1975. The western part was discovered first and the southern side is near the town wall. The luxury rooms are located in the eastern part. The 2nd, 3rd and 4th rooms all have mosaic floors. Between the 3rd and 4th rooms there is a hole that led to the eastern entrance of the residence. The hole was purposefully created between the 4th and 6th century. ==See also==
