The opening of the sanhedrin was delayed until Feb. 9, 1807, four days after the adjournment of the Assembly of Notables. Its seventy-one members included the rabbis sitting in the Assembly, to whom were added twenty-nine other rabbis and twenty-five laymen. Its presiding officers, appointed by the minister of the interior, were: Joseph David Sinzheim, rabbi of Strasbourg (president); Joshua Benzion Segre, rabbi, and member of the municipal council of Vercelli (first vice-president); Abraham de Cologna, rabbi of Mantua (second vice-president). After a solemn religious service in the synagogue, the members assembled in the Hôtel de Ville, in a hall specially prepared for them. Following the ancient custom, they took their seats in a semicircle, according to age, on both sides of the presiding officers, the laymen behind the rabbis. They were attired in black garments, with silk capes and three-cornered hats. The sittings were public, and many visitors were present. The first meeting was opened with a Hebrew prayer written by David Sinzheim; after the address of the president and of Abraham Furtado, chairman of the Assembly of Notables, it was adjourned. At the second sitting, Feb. 12, 1807, deputies Asser, Lemon, and Litwack, of the newly constituted Amsterdam Reform congregation Adat Jeshurun, addressed the sanhedrin, Litwack in Hebrew, the others in French, expressing their entire approval of the Assembly and promising their hearty support. But the deputies were greatly disappointed when the president, after having answered them in Hebrew, invited them to be silent listeners instead of taking part in the debates as the proclamation of the Notables had caused them to expect. Addresses from congregations in France, Italy, and the Rhenish Confederation, especially from Neuwied and Dresden, were also presented.
