Description
1 p.l., ten numbered leaves. Folio (285 x 190 mm.), attractive antique marbled boards. [Valencia: ca. 1750]. An interesting document that describes the founding of an association to support Valencia’s principal silk production facility. Beginning in the 15th century, Valencia built a robust silk industry thanks to close ties with Genoa, which exported silk to the eastern Mediterranean. Within a century, silk had become one of Valencia’s most important exports and by the 17th century the city had consolidated control over the harvesting and manufacture of silk fiber. The mass-production of woven silk helped revitalize the Valencian economy in the 18th century after a period of economic downturns. The present text is divided into 20 sections and lays out the group’s mission, responsibilities, and internal organization. One part is dedicated to the support of the factory’s workers and helping them avoid homelessness. Written in several legible hands and in a fine state of preservation.
