Original prompt & settings (JSON) ↗For two days the rebel fleet sat in full view of Constantinople while Phocas’s government disintegrated behind the walls.
Saturday, 3 October 610
On Saturday 3 October 610, ships carrying the younger Heraclius appeared off Constantinople near the Circular Fort, outside the walls by the Hebdomon.
That evening Emperor Phocas rode from the suburban palace at the Hebdomon into the imperial palace inside the city.
Heraclius stayed outside, in view of the capital, while divisions within Constantinople undermined organised resistance to his fleet.
Two more days
The overthrow did not happen on 3 October. Bonosus, Phocas’s commander, was killed by an excubitor on 4 October.
Phocas was seized and killed, and Heraclius was crowned by Patriarch Sergius, on Monday 5 October.
The Chronicon Paschale names Photius and Probus — not Heraclius — as the men who seized Phocas in the palace.
What the sources will not settle
They disagree about who killed Phocas. The Chronicon Paschale leaves the executioner unnamed, while John of Nikiu says Phocas was killed in Heraclius’s presence.
Heraclius the Elder, exarch of Africa, supported and led the revolt but remained in Africa; he did not accompany his son into Constantinople.
Nor did the state acquire a new name that day: calling the empire after 610 “Byzantine” is a modern periodisation convention.

What the sources leave uncertain
- The contemporary Chronicon Paschale securely dates the fleet’s appearance to Saturday, 3 October. Its manuscript gives the seizure of Phocas as the dawn of 6 October, but also calls the day Monday; editors correct this to Monday, 5 October.
- Sources disagree about who killed Phocas and the details of his mutilation. The Chronicon Paschale does not identify Heraclius as the executioner; John of Nikiu says Phocas was killed in Heraclius’s presence.
- Accounts differ over how much credit belonged to Priscus, the Excubitors and the Green circus faction; the surviving narratives may reflect later political self-presentation.
