Copperplate engraving, printed on hazelnut paper, period white lead, 230x380 mm. Wide margins, some blooming. Vianelli, of Venetian origin although born in Porto maurizio, moved to Naples where he became intimate with the famous painter Giacinto Gigante, together with whom he studied landscape painting taken from life, attending for a few months the school of Hueber, a German painter specialised in topographical shots of academic taste; together with Gigante, Vianelli and some of his other pupils, such as Alessandro Fergola and Gabriele Smargiassi participated in the Posilippo school. In the 1930s, he gradually abandoned landscape painting in oils to devote himself to perspective views of squares and church interiors, realised in watercolour technique and especially with sepia monochromes, of which he developed a valuable technique. Many of his views were reproduced in etching or lithographed and published in volumes dedicated to the city of Naples.
