STEP 11 - Un documento

Il Papiro di Stoccolma è la più antica testimonianza di testo alchemico e ricettario pervenutaci sulla lavorazione dell'argento, delle pietre preziose e delle stoffe.




Il papiro, probabilmente scritto a Tebe e risalente al tardo III secolo o ai primi anni del IV secolo, venne rinvenuto in un'antica tomba nel XIX secolo e in seguito trasferito a Stoccolma, acquisendo il nome odierno.
Tre delle ricette del papiro trattano il colore amaranto, come ricavarlo e come tingerne la stoffa.


96. Dyeing in Purple.
Purple. Roast and boil Phrygian stone. Leave the wool therein until it becomes cold. Then lift it out, put 1 mina (each) of archil and amaranth in another vessel, boil then and let the wool cool down in it.

99. Another (Recipe).
Phrygian stone is roasted and boiled. The wool is put in and left there until it becomes cold. Then lift it out, place in another vessel 1 part archil and 1 part of amaranth blossoms, boil it again, put the wool in and let it become cold there. Lift it out and rinse it with salt water.

128. Another (Recipe).
Purple. Phrygian stone is crushed and boiled. The wool is put in and left there until it becomes cold. Then lift it out. Put in another vessel 1 part of archil and 1 part of amaranth blossom, boil it again, put the wool in and leave it become cold there. Lift it out and rinse with salt water. An excellent mordant for purple comes from Phrygian stone; for a kotyle of wool (use) a kotyle of stones.
