Croce improved the instruments for trephination, and published classic woodcuts depicting the operation, including the first illustration of a neurological surgery operation actually taking place. The work is also important for Croce’s descriptions of cranial and cerebral diseases. In hundreds of woodcuts of instruments and procedures Croce illustrated all of the instruments used before and during his own time. Digital facsimile from the Internet Archive at this link.
