The following description was prepared by William Gross:
From earliest times, man has tried to protect himself from misfortune by the use of objects which he considered holy or otherwise (e.g., magically) potent. Amulets and talismans are Items generally worn around the neck or wrist, carried in a pocket or purse or hung on a wall. They are meant to protect or aid those who carried or wore them. The Hebrew word for amulet, kame‘a, has the root meaning "to bind". Jewish amulets are usually comprised of texts (either letters or graphic symbols) that are inscribed on some sort of material; some may also contain plant matter or precious stones. The texts of amulets usually include holy names that are believed to have the ability to affect reality, along with incantations summoning angels or other magical powers. For the most part, an amulet has a specific purpose: to ease childbirth, facilitate recovery from illness, improve one’s livelihood, and so on, but in the modern world many are also made for general protection.
Even after the appearance of the printing press, amulets continued to made by hand even til today. One of the forms of this is the scroll amulet, written on a long, thin piece of paper or parchment. When it was finished, it was rolled and placed into a container of textile. leather, or some metal and closed for easy carrying. These are individual amulets usually made for a specific person and for a specific need in addition to general protection.
This substantial amulet written on parchment is a birth amulet, but the name of the woman for whom it was written in not inscribed or was deleted, as sometimes happens when amulets are discarded. The amulet is done mostly in quite clear square script and is filled by angel names and varied "names" as well, including the 42 letter name, the names of the three angels and many others.
