This essay aims to bid analogue historians assume that digitisation is the first step to creating historical heritage based on the new language of Science: Computer Science. As we know, Humanities disciplines cannot easily be encapsulated in a few understandable numbers and names. However, historians must boost Artificial Intelligence (such as Transkribus) and Neural Networks to let the Machine infer meaning from the digitised historical primary source and become the most powerful tool to help historians understand what happened in the Past. Historians (collaborating with data scientists, expert annotators, librarians, archivists, and others, who are crucial to the successful management of digital data collection) have to create the primary ontology, starting from coding manuscripts into digital text, as the Biscari Archive (Italy) study case.
