Forsooth in the large entry of the porch shall be made a curtain of twenty cubits, of jacinth, and purple, and of red silk twice-dyed, and of bis folded again, by embroidery work; it shall have four pillars, with so many bases. (And at the entrance to the courtyard shall be a curtain twenty cubits long, made out of jacinth, and purple, and red silk twice-dyed, and finely woven linen, and embroidered; it shall be hung on four pillars, with as many bases.)
