The "Virtues" or "Strongholds" lay beyond the ophanim (Thrones/Wheels). Their primary duty is to supervise the movements of the heavenly bodies in order to ensure that the cosmos remains in order. The term appears to be linked to the attribute "might", from the Greek root dynamis (pl. dynameis) in Ephesians 1:21, which is also translated as "Virtue". They are presented as the celestial Choir "Virtues", in the Summa Theologica. Traditional theological conceptions of the Virtues might appear to describe the same Order called the Thrones (in which case the Ophanim may not be the same thing as "Thrones").
