The first of the Archangels of Malkuth is Metatron, which is also the name of the archangel of Kether. His name has no meaning in Hebrew (It is a Hebrew form of Mithras - the name of a Roman saviour-god of Persian origins).
Metatron is known as The Prince Of The Countenances - and represents a secret link connecting the highest and lowest of the Sephiroth.
Cabalistic traditions make a useful distinction between the aspect of Metatron assigned to Kether and that assigned to Malkuth - a distinction involving a different spelling of the Archangel’s name. Metatron in Malkuth is held to be the transformed Enoch, taken bodily into heaven according to biblical myth, and to function as a celestial scribe recording all the acts of humanity - his name was spelled MThThRVN.
Metatron in Kether, by contrast, is seen as a transcendent power, the ‘Lesser Tetragrammaton’ created before the birth of the universe and his name was spelled with an additional Yod - MIThThRVN. In either form, Metatron may be visualised as an angelic figure of pure light
