Life

Augustus was born at Dannenberg Castle, the seventh child of Duke Henry of Brunswick-Lüneburg (1533–1598).^[1] His father had ruled over the Brunswick Principality of Lüneburg, jointly with his younger brother William, since 1559. Ten years later, however, upon his marriage with Ursula, a daughter of the Ascanian duke Francis I of Saxe-Lauenburg, he had to waive all rights and claims and was compensated with the small Dannenberg lordship. Moreover, he received an annual payment and had reserved the inheritance right of his descendants should the Brunswick-Wolfenbüttel line become extinct.

Augustus, as the seventh and youngest child, had little chance to take up any rule in the Brunswick lands. He concentrated on his studies in Rostock, Tübingen, and Straßburg. Afterwards, he travelled on a Grand Tour through Italy, France, the Netherlands, and England. Back in Germany at the age of 25, he took his residence in Hitzacker, where he spent the next three decades with a small court, continuing his studies.

Succession arose in the midst of the Thirty Years' War, when the last Wolfenbüttel prince, Duke Frederick Ulrich of Brunswick-Lüneburg died without heirs in 1634. After lengthy and complicated negotiations with his reluctant Welf relatives and an intervention by Emperor Ferdinand II, it was finally agreed that Augustus should inherit the Wolfenbüttel principality. Because of the ongoing war, he had to stay at Dankwarderode Castle in Braunschweig and could not move to his residence until 1644. Soon after, Augustus instituted a number of government reforms, and founded the Bibliotheca Augusta (now the Herzog August Bibliothek). After the 1648 Peace of Westphalia, the Wolfenbüttel lands recovered quickly under his capable rule.

Augustus was a promoter of German as language of literature. Under the pseudonym Gustavus Selenus, he translated a book on rithmomachia by the mathematician Francesco Barozzi, wrote a book on chess in 1616, Chess or the King's Game, and a standard reference on cryptography in 1624: Cryptomenytices et Cryptographiae libri IX (Gustavi Seleni).^[2] The pseudonym itself is a cryptic reference to his name, Gustavus anagrams (with U=V) to Augustus, the surname is a play on the Greek goddess of the moon (Selene). The book on cryptography is largely based on earlier works by Johannes Trithemius and also describes the work of Abramo Colorni.^[3]

The duke employed the scholar Justus Georg Schottel as tutor of his sons; he also kept an active correspondence with Johannes Valentinus Andreae, a founder of the esoteric Rosicrucianism movement. In 1632 he met with Prince Louis I of Anhalt-Köthen and joined his Fruitbearing Society.

Augustus died at Wolfenbüttel and was succeeded by his eldest son Rudolph Augustus.
