When did Anastasia - wife of Constantine IV die?

While there is no definitive date for the death of Anastasia, wife of Constantine IV, most sources place it sometime between 711 and 718.

This is based on:

* Her absence from historical records after 711: The last mention of Anastasia in historical sources is from 711.

* Her son, Leo III, becoming emperor in 717: It's unlikely that Constantine IV would have chosen to put his son on the throne if his wife was still alive.

However, some sources suggest she may have lived longer, perhaps until 721.

It's important to remember that information about the Byzantine Empire in this period is limited, and there's no concrete evidence to confirm the exact date of Anastasia's death.
