Madness
The Gerasene demoniac is the fullest clinical description in the corpus: tombs, broken chains, self-injury, and a name that is a number.
Mark 5 is unusually detailed. The man lives among the tombs, cannot be bound even with chains because he tears them apart, cries out night and day, and cuts himself with stones. Asked his name, the spirit answers 'Legion: for we are many' — a Roman military unit of several thousand, which is either the size of the infestation or a political joke, and commentators have argued for both since.
What follows is equally specific: the man is found afterwards sitting, clothed, and in his right mind, which is the text's own measure of what was wrong. Elsewhere the Testament gives madness about women to Asmodeus, and the Hebrew Bible sends an evil spirit on Saul that only music relieves.

Who was blamed, and by which text?
Each card is one text making one attribution, in its own framing. Reading down the column is a transmission history rather than a set of independent witnesses — and where a claim carries a grading, that grading is about how well it is grounded in the passage it cites, nothing more.

Which texts make these claims?
Oldest first. The distance between the earliest and the latest is the thing worth looking at: a claim made in an incantation four thousand years ago and one made in a paperback in 1973 are different kinds of evidence about the same symptom.
