The Bulletin
In 1855, with his own money, he started to print in the Timon Printer, in Cagliari, his Sardinian Archaeological Bulletin (which was a collection of all the ancient monuments in Sardinia) at the same time with the spreading of Arborea Papers. This work was stopped in 1864 because of the scarce amount of subscribers and because of its cost, which was too expensive to the canonical: 500 liras par year. This publication is formed by ten volumes, the whole of it about two thousand pages, 540 articles of which 398 are signed by Spano, 5 are anonymous and 142 are signed by Spano’s friends and correspondents, embracing a period of time which goes from 1855 to 1864. Spano collaborated with local and Italian scholars: Pietro Martini, count Alberto Della Marmora (Royal Commissioner for Sardinia), Ignazio Pillito (antique dealer), François Bourgade (Chaplain of Saint Luis’ Imperial Chapel in Carthage), Salvatore Cossu (Ploaghe rector), Michele Amari (Public Schools Secretary in 1863), count Carlo Baudi of Vesme and many others. Many were the foreign correspondent, too, among whom, particularly, M. A. Levy (Maltzan baron who visited Sardinia in 1868), and G. Henzen (general minister of Archaeological Institute of Rome.
