[1] At university he also covered a wider range of subjects, including at this stage, middle eastern languages,[2] in which he was taught by Johann David Michaelis.

[2] Much of his "Grand Tour" is described in a volume that Bartels dedicated to his father and later published, entitled "Briefe über Kalabrien und Sizilien" ("Letters about Calabria and Sicily").

[4] He traveled home via Paris and the Netherlands, and shunning the offer of a professorship covering subjects for which he had become known, returned to the University of Göttingen in order to study Law, becoming a Doctor of Jurisprudence in 1790.

[1] In 1792 he returned with his friend Amandus Augustus Abendroth to Venice where he remained for long enough to claim as his bride Maria Elisabeth, the daughter of a banker called Johann Conrad von Reck.

In October 1792 his friend and traveling companion, Amandus Abendroth, married Johanna Magdalena von Reck, the sister of his own bride, just twenty days after his own marriage.

With this in mind, he published a summary of the main points of the 1712 document, using everyday language, and adding notes to provide historical and contextual clarifications.

The marriage of Johann Heinrich Bartels and Maria Elisabeth von Reck which took place in 1792 resulted in the recorded births of two daughters and two sons.
