A meticulous guide from the late‑seventeenth century, this work explains how mulberry trees are cultivated and how silkworms are raised for the production of silk. Commissioned by the Portuguese Prince Dom Pedro and prepared under the direction of senior officials, it mixes practical farming advice with the era’s broader vision of art and economy. The author stresses the value of silk as a modest‑cost treasure compared with mineral mining, presenting the craft as a profitable and refined addition to the kingdom’s resources.

Listeners will hear step‑by‑step instructions for planting mulberries, feeding larvae, and harvesting cocoons, alongside vivid references to the long‑standing Asian traditions that introduced the insect to Europe. The treatise also reflects on the cultural exchange between Persia, China, and the Mediterranean, illustrating how knowledge travelled alongside trade. Though the language is historic Portuguese, the text offers a clear window into early modern scientific practice and the ambition to enrich Portugal through the delicate art of silk.
