The London Canon Tables is a Byzantine illuminated Gospel Book fragment on vellum from the sixth or seventh century. It was possibly made in Constantinople. The fragment consists of two folios of two illuminated canon tables – of unusual construction – set beneath an ornamental arcade and the Letter by Eusebius of Caesarea which usually prefaces canon tables. The fragment is bound together with a twelfth-century Gospel Book which is thought to have belonged to one of the monasteries on Mount Athos.
