Cassiel

Cassiel originates from Hebrew and Latin angelological texts, where it names one of the archangels or ruling angels in Jewish and Christian mystical traditions. The name may derive from the Hebrew root 'kesah' (to cover or protect) combined with 'El' (God), giving the meaning 'shield of God'. It appears in medieval grimoires and kabbalistic writings and has been adopted into English use as both a given name and a literary name in recent centuries.

Cassiel belongs to a small group of angelic names that have crossed from mystical and religious texts into use as given names in the English-speaking world. In Jewish and Christian angelological traditions, Cassiel is described as one of the ruling angels of the heavenly spheres, associated with Saturn, the element of time, and the contemplative virtues of patience and solitude. His presence in medieval kabbalistic texts and European grimoires gave the name a learned, esoteric dimension that persists today. In England, angelic names began appearing in given name usage from the medieval period onward, though most remained confined to religious and scholarly contexts. The twentieth century saw renewed interest in angelology among New Age and alternative spiritual communities, bringing names such as Cassiel, Uriel, and Metatron into occasional use as personal names. In contemporary British culture, Cassiel remains exceptionally rare and carries an air of the extraordinary and the otherworldly. Its growing visibility is part of a wider trend for names that feel elevated and spiritually resonant without being overtly devotional.
