Through Constantinople, Cistern and Balkans

When Emperor Leo died in 474, his grandson Leo II (r. 474) took power, but soon died; his father, Zeno (r. 474–475, 476–491) ascended the throne in the same year, in a politically precarious position. Verina conspired to install the magister officiorum Patricius, her lover, as emperor. This plot was supported by Basiliscus, who succeeded in recruiting Isaurian brothers Illus and Trocundes, as well as Verina's nephew Armatus. Zeno fled on 9 January 475, either after learning of the plot or after Verina warned him that his life was in danger. Although Patricius was Verina's intended successor, Basiliscus convinced the Eastern Roman Senate to acclaim him instead.

Basiliscus quickly lost the support of his subjects and of his allies in court. Verina was alienated by the execution of Patricius, while the people objected to a combination of heavy taxes, heretical policies, and a natural disaster viewed as divine wrath for said heretical views. In an attempt to increase support, Basiliscus embraced the miaphysites, restoring Timothy Ailuros as the Patriarch of Alexandria and Peter the Fuller as Patriarch of Antioch. He heeded their advice and issued an encyclical on 9 April 475 which promoted the first three ecumenical councils of the church: Nicaea, Constantinople, and Ephesus, and condemned the Council of Chalcedon and the Tome of Leo. The Patriarch of Constantinople, Acacius, strongly opposed him, and together with Daniel the Stylite, turned the population of Constantinople against Basiliscus.

Zeno, besieged by Illus and Trocundes in his homeland of Isauria, convinced the two generals to defect, and soon the three of them marched their troops toward the capital. Basiliscus ordered Armatus to intercept them, but Armatus also switched sides after Zeno promised to give him the position of magister militum praesentalis for life, and make his son Basiliscus caesar. With Armatus's defense force deliberately kept out of his way, Zeno entered Constantinople unopposed in August 476. Basiliscus and his family hid in a church until Zeno promised not to execute them; exiled to Limnae in Cappadocia, they were either beheaded or imprisoned in a dried-up cistern and left to starve to death.

Life

Early life and family

Basiliscus was born at an unknown date, likely in the Balkans. He was the brother of future Empress Verina, the wife of East Roman Emperor Leo I (r. 457–474). Historian Stefan Krautschick argues that since Basiliscus's nephew, Armatus, was the brother of a barbarian named Odoacer, Basiliscus was therefore also the uncle of Odoacer and thus a barbarian; this argument has been opposed by historians Wolfram Brandes, and Hugh Elton. Elton remarks that Krautschick's argument relies upon a single fragmentary Greek source, making his argument acceptable, but ignores the total lack of contemporary sources mentioning his ethnicity or relationship to Odoacer. Basiliscus married Zenonis, and with her produced a son, Marcus. Zenonis's origins are unknown, but she may have been a miaphysite, as some authors credit her for pushing Basiliscus's religious policies. Basiliscus was also related by marriage to Emperor Julius Nepos (r. 474–475/480), as the uncle of Julius Nepos's wife. Zenonis is alleged to have taken Armatus, Basiliscus's nephew, as a lover. Byzantist J.B. Bury, summarizing sources from the Suda, Candidus, and Malchus states that:

Basiliscus permitted Armatus, inasmuch as he was a kinsman, to associate freely with the Empress Zenonis. Their intercourse became intimate, and as they were both persons of no ordinary beauty they became extravagantly enamoured of each other. They used to exchange glances of the eyes, they used constantly to turn their faces and smile at each other; and the passion which they were obliged to conceal was the cause of dule and teen. They confided their trouble to Daniel, an eunuch, and to Maria, a midwife, who hardly healed their malady by the remedy of bringing them together. Then Zenonis coaxed Basiliscus to grant her lover the highest office in the city.

Military career

Leo rose to the throne of the Eastern Roman Empire in 457 after the death of Emperor Marcian (r. 450–457). Aspar, the magister militum, selected him for this position, much as he had selected Marcian himself. Despite being half-Alanic and half-Gothic, Aspar held much influence in the empire since the mid-fifth century, and wielded significant power over Marcian and Leo. Basiliscus served as a military officer under Leo, and was made consul of the East for 465, with Flavius Hermenericus as consul of the West. Basiliscus was granted the rank of magister militum per Thracias in c. 464, and held it till 467/468; during this period he won many victories in Thrace against the Huns and Goths. He led troops in a war against a mixed group of the two in 466/467, along with Anagast, Aspar, and Ostrys. He was made a patricius at some point, first mentioned as such in 468.

Around 466, Leo attempted to free himself of Aspar's control. He utilized the support of the Isaurians, marrying the Isaurian chieftain Zeno (r. 474–475, 476–491) to his daughter Ariadne, in exchange for support. This resulted in a significant change to eastern imperial policy, notably ending the policy of ignoring the requests from the West for military aid. After Anthemius (r. 467–472), Marcian's son-in-law, was installed by Leo as Western emperor on 12 April 467, an embassy was sent to the Vandal King Gaiseric, to inform him as well as warn him not to interfere in Italy or the Western Roman throne; Gaiseric accused them of violating a prior treaty, possibly enacted in 433, and prepared for war. Rumors may have spread in Constantinople that the Vandals were preparing an invasion of Alexandria. As a result of this, in 468 Basiliscus was given command of an expedition against the Vandals, and likely promoted to magister militum praesentalis at that time. It is said that the fleet consisted of 1,113 ships, with more than 100,000 men under the command of Basiliscus, including mercenaries from as far as Öland, Sweden. According to Bury, Leo was influenced by both Verina and Aspar in his selection of Basiliscus, whom he describes as both "incompetent and untrustworthy"; he further states that Aspar intentionally chose a poor commander, to prevent Leo from becoming stronger by way of weakening the Vandals. Historians Gerard Friell and Stephen Williams dismiss this, but accept that Verina pushed for his appointment and that Aspar did not object. Historian Peter Heather points out that, at this point, Basiliscus had just returned from considerable success on the Balkan frontier of the empire.

Marcellinus, a West Roman commander, was sent to capture Sardinia, and then to sail to link up with the Eastern armies near Carthage, the Vandal capital. Basiliscus was to sail with the bulk of the forces directly to Carthage, and the Eastern comes rei militaris Heraclius of Edessa was to gather up Eastern forces in Egypt, disembark in Tripolitania, and then to approach Carthage by land; this way, the Vandals were forced to fight in three areas. Marcellinus seized Sardinia with little trouble, and Heraclius took the fortress of Tripoli, Libya, and both headed to connect with Basiliscus's forces. Basiliscus's galleys scattered the Vandal fleet near Sicily, something said by Procopius to have caused Gaiseric to give all up for lost, fearing a decisive blow to capture Carthage. However, Basiliscus did not press his advantage and rested his forces in Cape Bon, 60 kilometres (37 mi) from Carthage. This was a strategic location as it was near the port of Utica, which, unlike Carthage, was not blocked off with a chain, and the winds would push opposing ships into the coast. According to historians Michael Kulikowski, Friell, and Williams, Gaiseric feigned interest in peace and proposed a five-day truce, in order to allow himself time to prepare. Basiliscus accepted, possibly in favor of Aspar who opposed the war, in order to achieve a compromise with the Vandals. Heather notes that the Romans strongly intended to avoid a naval engagement, and archaeologist George Bass suggests this might be the reason that Basiliscus hesitated to strike the Vandals.

Gaiseric assembled a new fleet with a number of fire ships and, aided by good winds, attacked the Roman fleet at the Battle of Cape Bon. The Roman fleet was routed by the combination of the fire ships, bad winds, and surprise, with half of it being destroyed. Basiliscus fled with the remainder of the fleet to Sicily, to consolidate with Marcellinus's forces; their morale and supply might have brought a victory, but Marcellinus was assassinated, possibly on Ricimer's orders. Heraclius, who had not yet reached Carthage, returned to the Eastern Roman Empire by the path he came, and Basiliscus returned to Constantinople. The total cost of the armaments for the fleet was 130,000 pounds (59,000 kg) of gold, more than the entire treasury of the Eastern Empire, causing the Eastern Empire to waver above bankruptcy for more than 30 years.

Upon his return to Constantinople, Basiliscus sought refuge in the Church of St. Sophia, before Verina interceded on his behalf to have him pardoned by Leo. He may have remained magister militum praesentalis after this, but largely lived a life of retirement at Heraclea on the Propontis. Aspar was suspected of inducing Basiliscus to betray the expedition, sympathizing with the Vandals, and promising to make him emperor in place of Leo. Friell and Williams also reject this, commenting that the need to find a scapegoat is common in such disasters and that the accusation is implausible. One source, Hydatius, states that Aspar was stripped of his rank for voicing his suspicions, but historians A. H. M. Jones, John Robert Martindale, and John Morris state that this is almost certainly a confusion relating to the disgrace of Ardabur, his son, who had informed the Sassanid Empire of Roman military weakness.

Aspar regained power after the failure of the African invasion, and his son Patricius became the presumptive heir to the throne by marrying Leo's daughter Leontia Porphyrogenita in 470. Historian L. M. Whitby suggests this may have been a ploy to lull Aspar into a sense of security. When anti-German sentiment rose up, Leo first quarreled with Aspar and then had him assassinated over suspicions of conspiracy. Basiliscus supported Leo in his power struggle against Aspar, and subsequently Theodoric Strabo, in 471/472. Aspar and Ardabur were killed in 471, and Patricius, severely wounded, was stripped of his position as caesar and divorced from Leontia. After this, Zeno gained more power over the court. Theodoric Strabo attempted to avenge Aspar and marched against Constantinople, but was pushed back by Basiliscus and Zeno. A little later, he sent a series of demands to Leo in the capital and attacked Arcadiopolis and Philipopolis, but was forced to negotiate soon after due to the lack of supplies.

Rise to power

When Leo fell ill in 473, he had his grandson, Leo II (r. 474), the son of Zeno and Ariadne, crowned as emperor in October 473. Leo died on 18 January 474, and Leo II took the throne. Zeno was installed as co-emperor, crowned on 29 January, and when Leo II died in Autumn, Zeno became the sole eastern emperor. Zeno likely had Theoderic Strabo stripped of his role as magister militum praesentalis. Zeno was very unpopular, among both the common people and the senatorial class, in part simply because he was an Isaurian, a race which had acquired a poor reputation under Emperor Arcadius (r. 383–408), and also because his rule would induce a promotion of fellow Isaurians to high positions.

Although Verina had supported Zeno's elevation as co-emperor to Leo II, she turned against him once he became sole emperor. The causes for this are disputed. The Byzantists Bury and Ernst Stein suggest this was motivated by personal hatred, and Ernest Walter Brooks, historian and scholar of the Syriac language, suggests the Isaurian background of Zeno directly caused the hatred of Verina and the people. Historians Kamilla Twardowska and W. D. Burgess argue that his ethnicity likely exacerbated existing hatred, but did not solely cause it. Twardowska also dismisses Evagrius Scholasticus's suggestions, especially that of him leading a "dissolute life", stating that is common of historians wishing to paint an emperor in a bad light. Historian Mirosław Leszka attributes the action to a simple desire for power, and Twardowska theorizes that Verina supported him while Leo II was emperor because she would still retain influence as a close relative, which she would not wield over Zeno himself. Zeno had the option of raising another son from a previous marriage to the throne, or else his brother, Longinus, which would remove any remnant of Verina's influence. Byzantine chronicler John Malalas states that Verina put forth a request which Zeno denied, causing her conspiracy, but does not specify the request; historian Maciej Salamon has argued that this request would be to have Basiliscus and her other relatives placed in high positions.

Verina conspired with others to remove him as emperor, and historians generally accept that she planned to install her lover, the magister officiorum Patricius, as emperor and to marry him. She was supported in this plot by Theoderic Strabo, angered by Zeno's coronation, and Basiliscus, who succeeded in recruiting Illus and Trocundes, Isaurian brothers, as well as her nephew Armatus. The plot had the backing of the military, bolstered by Basiliscus's popularity, and that of Illus and Trocundes, and also the support of the Eastern Roman Senate. The position of the Patriarch of Constantinople, Acacius, is unclear, although Twardowska considers it likely that he would have withheld support from either side until the outcome was clear. The exact date the conspiracy began is unknown: Salamon argues it began around 473, whereas Twardowska argues it began only after Zeno took sole power. The conspiracy was successful, as Zeno fled to his native Isauria on 9 January 475, either after learning of the conspiracy or after being convinced by Verina that his life was in danger, taking with him a number of companions and funds. Many remaining Isuarians were massacred in Constantinople when news of his flight spread. Basiliscus convinced the senate to acclaim him emperor, instead of Patricius, and Basiliscus was crowned at the Hebdomon palace. He immediately had his son, Marcus, crowned as Caesar, and later co-emperor, while his wife was crowned Augusta and Patricius was executed. Zeno took residence in the fortress of Olba, and later Sbida. Illus and Trocundes were sent by Basiliscus to lay siege to Zeno's fortress, and capturing Longinus, whom Illus would not release until 485.
