Note 347 — Chapter VI · THE COMMERCIAL INTERESTS AND POLICY OF THE GREATER GUILDS IN FLORENCE.338
Linda Villari translation
It would seem that the Guild of Por' Santa Maria originally traded in Florentine woollen stuffs, and that the silk merchants formed a secondary and separate branch. Gradually, however, they became amalgamated with the guild (early in the thirteenth century), and then became its principal components, until at last the Silk Guild and Por' Santa Maria were entirely fused in one.
