In 1238 he was named captain to defend the town of Gavardo against the forces of Frederick II, Holy Roman Emperor.
His first work was De amore et dilectione Dei et proximi et aliarum rerum et de forma vitae ("On love and delight in God and in neighbor and other matters concerning the rule of life"; 1238), a treatise on Christian conceptions of life under religious rule which quotes frequently from Seneca the Younger's Epistulae morales ad Lucilium (64 AD).
In total he was the author of three major treatises and five ‘sermons’, public addresses to his fellow causidici at their professional meetings.
Albertanus read and was influenced by Seneca the Younger, Cicero, St. Augustine, the Wisdom literature of the Old Testament, and some 12th century authors.
There were many translations of his works into French, German, Tuscan, Venetian, Spanish, Catalan, and Dutch, with a wide circulation well into the 15th and early 16th centuries, a testament to his broader influence on society.
