The young Triqueti carefully drew in ink, in 2 or 3 columns, the list of the sovereigns of the states of Europe, drawing in pen the coat of arms of each state, and drawing in pen and watercolor the maps: France (plus list of départements, one corner missing, map), Germany (14 coats of arms, from Austria to Hungary), England (2 maps: England and Scotland, and Ireland), Denmark (map), Spain (map), Poland, Portugal (map), Prussia, Russia, Sardinia and Savoy, Sicily, Sweden, "Turkey of Europe", Doges of Genoa and Venice. Provenance: Château du Perthuis. Note: Michel Triquet, who became Baron Michel de Triqueti (Henry's father), married Anne Marie Henriette Sophie de Salis-Samade in his second marriage, and settled with his family in the estate "Le Perthuis", near Montargis, which he bought in 1787. Anne Marie's father, Joachim (1747-1822), was already a prominent figure in the Montargis area, as owner of Château de Vaugouard and mayor of Fontenay-sur-Loing.
