I was strolling through the Wikipedia page on bronze and found a picture of bronze nails from Roman times. Under the picture is a text saying
Roman bronze nails with magical signs and inscriptions, 3rd-4th century AD
What would a Roman want to achieve with these writings? I know they sometimes used nails on a curse tablet, is there a source describing these practices and their reasoning?
The Wikipedia page on Curse Tablets only makes mentions of nails being used to pierce said tablets but not that they themselves are used like a tablet.
