The principal authorities for the following work are the four volumes of Correspondence published by M. Arneth, and the six volumes published by M. Feuillet de Conches. M. Arneth's two collections[1] contain not only a number of letters which passed between the queen, her mother the Empress- queen (Maria Teresa), and her brothers Joseph and Leopold, who successively became emperors after the death of their father; but also a regular series of letters from the imperial embassador at Paris, the Count Mercy d'Argenteau, which may almost be said to form a complete history of the court of France, especially in all the transactions in which Marie Antoinette, whether as dauphiness or queen, was concerned, till the death of Maria Teresa, at Christmas, 1780. The correspondence with her two brothers, the emperors Joseph and Leopold, only ceases with the death of the latter in March, 1792.
