The Book of Protection: Being a Collection of Charms is a collection of East Syriac Christian charms and incantations associated with the so-called 'Nestorian' Church (today's Assyrian Church of the East),[citation needed] edited and translated by Hermann Gollancz from three Syriac manuscripts which date back to early 19th century and earlier.

The owner was possibly a priest or some kind of officer of the Nestorian Church to whom men made application for spells, incantatory prayers and formulae of blessing to help them both spiritually and physically.

[citation needed] The two manuscripts in Gollancz's possession, were first brought to public notice at the International Congress of Orientalists held at Paris in 1897.

The charms range from antidotes to headaches, colic and 'teeth chattering' to prayers for protecting flocks, herds and possessions generally; for controlling mad dogs, unruly cows and 'the gun of warriors', as well as for warding off the evil eye.

Codex C shows that the compiler, like the Hebrews in Kabbalah, Samaritans and Ethiopians, believed firmly in the power of a spell cast in the names of the archangels and angels.
