The 18th century witnessed a rapid development of analysis, and the period culminated with the genius of Lagrange and Laplace.
His father, Joseph Louis Lagrange, married Maria Theresa Gros, only daughter of a rich physician at Cambiano, and had by her eleven children, of whom only the eldest (the subject of this notice) and the youngest survived infancy.
See also Kuenen's National Religions and Universal Religions (Hibbert lectures) and Lagrange's Etudes sur les religions simitiques (2nd ed.).
Of this school, which had Lagrange for its professor of mathematics, we have an amusing account in the life of Gilbert Elliot, 1st earl of Minto, who with his brother Hugh, afterwards British minister at Berlin, there made the acquaintance of Mirabeau.
The genius of Lagrange did not at once take its true bent.
