[1][2] On 4 July 1549 Bizzarri was admitted a Fellow of St John's College, Cambridge, by the royal commissioners for the visitation of the university, being incorporated there ad eundem; and Francis Russell became his patron.
[1][2] Bishop John Jewel, prompted by Archbishop Matthew Parker, gave Bizzari the prebend of Alton Pancras in Salisbury Cathedral.
He obtained, in 1570, a license from William Cecil to go abroad, to print his own works, and gather news of foreign affairs for the government.
He passed some time at Genoa; in Germany he obtained, through the influence of Hubert Languet, employment with the Elector of Saxony.
In 1581 he asked Justus Lipsius in Leyden to find a publisher of his "Universal History" in eight volumes.
