👉 A testimonium, also known as a witness or a witness's statement, is an account of an individual's testimony that has been recorded and preserved for historical record. This type of document serves as a formal representation of someone's knowledge, beliefs, or actions, often providing evidence to support the testimony of another person. The term "testimonial" comes from Latin, meaning "testifying." In legal contexts, witnesses are considered to be the individuals who provide firsthand accounts of events that were witnessed by others
