service. Minutoli had married Freiin Mathilde von Rotenhan (1812–1878) in 1834, and they had had four children. After his resignation, he and his family moved to Franken, probably living in his wife's house in Rentweinsdorf and perhaps occasionally also in Bamberg. During this time, he studied the history of Hohenzollern and Brandenburg, as well as producing his memoirs, that were forbidden in Prussia. After being without a position ever since his resignation, in 1851 he entered the diplomatic service and became Prussian consul general for Spain and Portugal. Making several businesses trips to Barcelona, Spain, Portugal and the Canary Islands subsequently featured in his writings. He returned to Berlin in 1859 and was dispatched again the following year as a Prussian Minister-resident and consul general to Persia. He died on 5 November 1860 during a business trip to the Persian Gulf in a Caravanserei in Shiraz, probably of cholera, and was buried in the cemetery of the Armenian Christian community there. Cultural activities Already during his time at Posen, just as on his later trips, Julius made numerous sketches of persons, building and events, some of which he sold and some of which he gave to Friedrich Wilhelm IV gave, and with which he made his name even now until today a name as a draughtsman. During his time in Franken he maintained close contacts with the leading Bamberg circles in science and culture, especially history and natural science, establishing its Naturalienkabinett (now the Naturkundemuseum) and contributing numerous exhibits to other museums. He maintained extensive correspondence, among others, with the "Prussian Court-Modeller" in Bamberg Carl Schropp, the collector Emil Freiherr Marschalk von Ostheim and the archivist Paul Oesterreicher. A lavender-type growing on the Canary Islands was named "Lavandula minutolii" in May 1860 by the botanist Carl Bolle in Julius's honour.
