As early as 1860 Desor thought he had discovered indications of a palafitte in Lake Maggiore,[39] but this was subsequently disproved, and up to the present time no remains of these ancient dwellings have been found in this lake. The explanation of their absence in the larger lakes of Italy is to be found in the physical conditions of these glacial and rock-cut basins, which, owing to the depth of water and their rapidly-shelving shores, afford no holding for piles.
Stoppani, in his first exploratory tour, turned his attention to Lago di Lecco as, in his opinion, a suitable locality, and having found a group of piles half-way between the Bridge of Lecco and Malgrate stretching towards the western shore, he concluded this was "una bella palafitta a cui nulla mancherebbe per ritrarre perfettamente quelle della età del bronzo." The only resemblance of this supposed palafitte to those of the Bronze Age was the fact that the tops of the piles projected 1 or 2 feet above the lake mud, as no relics of any kind were found. Further researches have not confirmed the genuineness of this palafitte, and Regazzoni throws out the hint that the piles observed by Stoppani might be the work of modern fishermen, who are in the habit of inserting stakes for fixing their nets and which, among themselves, go under the name of serrade or gueglie. (B. 67 and 327, p. 70.)
LAKE OF ANNONE.
In the narrow strait which connects the small lake-basins of Sale and Annone, Stoppani found some piles projecting from a heap of stones in a depth of 6 or 7 feet of water, which he took to be indications of a palafitte. In 1877 Castelfranco (B. 307) re-examined the locality, and came to the conclusion that the submerged piles and stones observed by Stoppani were merely the remains of a bridge which, at some former period, connected the peninsula Isella with the southern shore; and so the matter still rests.
LAKE OF PUSIANO.
More satisfactory discoveries were, however, made by Stoppani in his preliminary tour in the Lake Pusiano, where, at the north end of the Isola dei Cipressi, he recognised the existence of a pile-dwelling. The genuineness of this station has been confirmed both by Castelfranco and Regazzoni, who had subsequently made some investigations in the locality. The industrial remains were confined to a few objects of flint-saws, scrapers, flakes, and arrow-points, a portion of a terra-cotta whorl, and some bones and teeth of animals. In 1877 Regazzoni found piles at the other end of the Isola dei Cipressi buried in a heap of stones. (B. 327, p. 72.)
TORBIERA DI BOSISIO.
To the east of Lake Pusiano lies the torbiera di Bosisio, which came early under the notice of archæologists by the discovery in it, at a depth of 10 feet, of a beautiful bronze axe-head ([Fig. 51], No. 10). Since then a great many relics have been from time to time found in this peat, but they have been widely dispersed, and as the deposit is now nearly exhausted no more finds can be looked for. Sig. G. B. Villa,[40] in his descriptive notices of this peat moor, speaks of arrow-points, burnt wood, bits of straw, trunks of trees, etc. Among other things which have been sent to different museums are a bronze spoon (No. 11), (probably of much later date than the other objects), some beautiful arrow-points (Nos. 1 to 7), and a lance-head of flint. An iron hook of modern shape was found at a depth of 3 feet. (B. 327, p. 97.)
