Mommsen, in his work De Collegiis et Sodalitiis Romanorum, says that under the emperors no guild was allowed to hold meetings, except by special laws, yet though new companies were not to be formed, the existing ones of architects and artisans were permitted to continue after public liberty was lost. Several documents prove that the chief scope of these unions was to promote the interests of their art, to provide mutual assistance in the time of need, to succour the sick and poor, and to bury the dead.
The trade guilds in London, the Arti in Florence, and the town clubs kept up in England till lately, seem to be all survivals of these ancient classical societies.
Besides the Builders' Society, Como had, in Roman times, a nautical guild. An inscription is extant, dedicated to C. Messius Fortunatus by the Collegium nautarum Comensium. This guild sent twenty ships of war to Venice in Barbarossa's time.
But besides having privileged societies, Como and its Comacine islands were a privileged territory, and might almost have been called a republic. We have, it is true, no documentary evidence of this dating back to pre-Longobardic times, but as Otho in 962[18] confirmed the islands in all former privileges granted by his predecessors on the Imperial throne, we may fairly suppose the privileges dated from times far anterior to himself.
This is an anglicized version of his decree, which was granted on the petition of the Empress Adelaide—
"In the name of the Holy and indivisible Trinity, Otho, by the will of God, august Emperor. If we incline to the demands of our faithful people, much more should we lend our ear to the prayers of our beloved consort. Know then, all ye faithful subjects of the Holy Church of God, present and future, that the august Empress Adelaide, our wife, invokes our clemency, that for her sake we receive under our protection the inhabitants of the Comacine islands, and surrounding places known as Menasie (sic), and we confirm all the privileges which they have enjoyed under our predecessors, and under ourselves before we were anointed Emperor, viz. they shall not be called on for military service, nor have arbergario (taxes on roads and bridges), nor pay curatura (tax on beasts), terratico (tax on land), ripatico (on ships), or the decimazione (tax on householders) of our kingdom, neither shall they be obliged to serve in our councils, except the general assembly at Milan, which they shall attend three times a year. All this we concede, etc. Given on the 8th before the calends of September, in the year of the Incarnation 962, first year of the reign of the most pious Otho."—Indiction V. in Como.
The hypothesis that this decree refers to a long-existing liberty is confirmed by the history of Como in the time of Justinian I. Up to the middle of the sixth century a certain Imperial Governor of Insubria, named Francione, who had seen Rome sacked and his own state taken, fled to Comacina as a free place of refuge when Alboin invaded Italy. He helped the Comacines to hold out against the barbarians for more than twenty years, and so secure was the place considered that the island was by Narses and others made the depositary of infinite treasures. With him multitudes of Romans had taken refuge there, but finally even this fell into the hands of the Longobards. We are told that Autharis subjugated Istria, and after a six months' siege, possessed himself of the very strongly fortified island of Comacina on the lake of Como, where he found immense treasures, doubtless part of the traditional wealth amassed by Narses, and which as well as much private property had been deposited here for security by the neighbouring peoples.[19]
Here then, four centuries before Otho's decree, we have Comacina as a place of refuge in troublous times, chosen because, being a free city, it was considered more safe than other towns. We need not then consider it improbable, if in the dark centuries when the Roman Empire was dying out, and its glorious temples and streets falling into ruin under the successive inroads of half-savage despoilers; when the arts and sciences were falling into disuse or being enslaved; and when no place was safe from persecution and warfare, the guild of the Architects should fly for safety to almost the only free spot in Italy; and here, though they could no longer practise their craft, they preserved the legendary knowledge and precepts which, as history implies, came down to them through Vitruvius from older sources, some say from Solomon's builders themselves.
Among the treasures must have been works of Greek and Roman art, that kept alive the old spirit among the guild of builders gathered there; but alas! after the long generations when art was decaying, and uncalled for, their hands lost their skill, they could no longer reproduce the perfect works.
