Before a single thread could be woven, flax had to be grown, harvested, and processed through a sequence of steps that took several months and demanded close attention to soil, water, and weather. In Lombardy, these steps were shaped by the region's particular combination of irrigated lowland agriculture, alpine river systems, and a dense network of small landholdings that characterised the area from at least the 14th century.
The Agricultural Context
Linen production in Lombardy was never an industrial enterprise in the modern sense. It operated within a system of mixed farming in which flax was one of several cash crops grown alongside wheat, millet, and legumes. Agricultural surveys from the territories of Bergamo, Brescia, and the Milanese hinterland — compiled in the 16th and 17th centuries by civic and ecclesiastical administrators — record flax cultivation as a standard component of small-farm activity, typically occupying between a quarter and a third of a holding's arable land in years when the crop was grown.
The variety cultivated was almost universally Linum usitatissimum, the common flax, grown specifically for its long bast fibres rather than its oilseed. Seed selection records from the Abbey of Chiaravalle near Milan indicate that by the 15th century, local farmers distinguished between varieties on the basis of stem length and fibre fineness, selecting for taller-stemmed plants suited to fine linen rather than the shorter varieties used for linseed oil production.
Soil Preparation and Sowing
Flax placed demanding requirements on the soil. It needed a well-drained, moderately fertile ground — too rich a soil produced coarse fibres; too poor a soil reduced yield significantly. Contemporary farming manuals, including sections of the late 16th-century Lombard agricultural text compiled by Agostino Gallo, describe the preparation of flax ground in terms that reflect long practical experience: two or three deep ploughings in autumn, followed by a final lighter preparation in spring, with the addition of well-rotted manure from the previous autumn's composting.
Sowing took place in April, as soon as the risk of ground frost had passed. The seed was broadcast densely — more densely than wheat — because crowded growth encouraged the plants to put their energy into upward stem development rather than branching, producing the long, straight stems that yielded the longest bast fibres. Gallo's text specifies seed rates of roughly 15 to 18 litres per Lombard plough-land, which corresponds to approximately 2.4 to 2.9 bushels per acre in contemporary English equivalents.
Harvesting
Flax was harvested before full seed ripeness — at the point when the lower third of the stem had turned yellow and the seed bolls were still green or just beginning to brown. Harvesting at this stage preserved the maximum length of the bast fibres; waiting until full ripeness allowed the fibres to over-mature and become brittle. The plants were pulled by hand rather than cut, to preserve the full length of the stem from root to tip. Harvesting records from estates in the Brescian lowlands in the 17th century describe teams of eight to twelve workers completing a field of roughly 1,200 square metres in a single day, with the pulled stalks laid in rows and tied in bundles before drying.
Retting: Separating Fibre from Stalk
Once harvested and dried, the flax bundles underwent retting — the controlled biological process by which the pectin binding the bast fibres to the woody core of the stem was decomposed, allowing the fibres to be separated without damage. Two methods were used in Lombardy, often in combination depending on the season and the intended quality of the linen.
Water Retting in the Irrigation Channels
The most common method in the lowland districts was water retting in the region's extensive system of irrigation channels and drainage ditches. Bundles of dried flax stalks were submerged in slow-moving or still water for periods of ten to twenty days, held down with weighted frames or stones to prevent them from surfacing. The anaerobic bacterial action of water retting was rapid and produced long, soft fibres, but also generated a strong smell from the fermentation process, which made it a source of documented conflict in areas where the same water channels served multiple agricultural and domestic purposes.
Civic records from Bergamo from the 15th and 16th centuries include repeated ordinances regulating when and where flax could be retted in channels near settlements, reflecting the tension between linen production and the shared use of water. The 1482 Bergamo statutes specifically prohibited retting within 500 braccia of a mill or town fountain during summer months.
Dew Retting on Open Ground
In the foothills and the higher-altitude communities along the Alpine fringe, where standing water suitable for channel retting was less available, dew retting was the standard practice. Dried flax bundles were spread in thin, even layers across open meadows or harvested fields in late summer and early autumn, where overnight dew and morning moisture, combined with fungi and bacteria naturally present in the soil, gradually broke down the pectins over a period of three to six weeks.
Dew retting produced a slightly coarser fibre than water retting — less consistent in colour and separation, but requiring no infrastructure beyond a suitable open field. It also posed less risk to water supplies, which may explain its persistence in communities that had access to both methods. Accounts from the valleys of the Bergamesque Alps in the 17th century describe meadow retting as the standard practice for domestic linen production, with water retting reserved for larger, commercially-oriented operations in the lowlands.
After Retting: Breaking and Scutching
Following retting, the flax was dried again and then subjected to breaking — the mechanical crushing of the woody stalk core using a wooden-jawed implement called a gramola in Lombard dialect — followed by scutching, in which the broken woody fragments (shives) were beaten from the loosened fibre bundles. The residual fibre was then drawn through iron-toothed heckling combs of progressively finer gauge to remove the last fragments of stalk and to align the long bast fibres into a parallel bundle ready for spinning.
Agricultural estate accounts from the late 17th century in the territory of Brescia record these stages as distinct hired tasks, suggesting that by this period the processing chain had become partially specialised, with different households or workshops handling retting, breaking, and hackling as discrete operations rather than the integrated farm-level sequence characteristic of earlier centuries.
