English version of the author's original Scots text.

The work is usually attributed to John Macollo (Maccollo, Mackullo, Maculo, etc.), although according to Innes Smith his brother James was also physician to James I and it is not clear whether there is independent evidence to connect either brother with Rudolf II.
