Hashmal

The Hashmallim (חַשְׁמַלִּים chashmalim; sing. Hashmal, חַשְׁמַל chashmal) are angelic entities in Judaism.[1]

Ezekiel's "chariot vision", by Matthaeus Merian (1593-1650).

The word hashmal appears in the Hebrew Bible in Ezekiel 1:4:

I saw, and behold, there was a stormy wind coming from the north, a great cloud with flashing fire and a brilliance surrounding it; and from its midst, like the color of the Hashmal [often translated electrum] from the midst of the fire, and in its midst there was the likeness of four Chayot חיות (living creatures).

Hashmallim occupy the fourth rank of ten in Maimonides's exposition of the Jewish angelic hierarchy.

The Septuagint translates "hashmal" to ηλεκτρον (elektron), which means "amber" in English. Francis Bacon coined the English word "electricity" to describe the static electric effect of rubbing amber with cloth. Later, "hashmal" became the modern Hebrew word that translates to the English word "electricity." Jewish poet Judah Leib Gordon coined the modern Hebrew word, in his 1878 collection Gabashta.[2]
