The work, in addition to being a piece of furniture of precious artistic value, can be considered a remarkable technological work of the eighteenth century; it is a writing desk with an extendable top, equipped with a lectern with a rotating system of bookshelves.

The rotating lectern, which typologically refers to the Nordic medieval tradition, belonged to the Library of Queen Maria Carolina of Austria, and documents the presence in Naples of foreign artists and artisans who gravitated around the Court, importing and disseminating craft techniques and a variety of models. The signature 'Giovanni / Uldrich - Year 1792', shown on the gilt bronze plaques of the support surface, points towards an Austrian or German origin of the craftsman, who is also active as a piano maker.

The work is influenced by the neoclassical taste that gives the structural elements the shape of the architectural orders: the supporting columns of the large central wheel assume Doric shapes and the capitals rigorous classical lines. On one side of the table top, also of classic shapes, a metal crank allows the movement of a sort of 'mill' with two wheels, to which eight shelves-lecterns are fixed with adjustable brass hinges. , which allow the simultaneous reading of multiple texts.
