THE WAY TO CONSTRUCT A FRAME-WORK FOR DECORATING BUILDINGS.
The way in which the poles ought to be placed for tying bunches of juniper on to them. These poles must lie close to the framework of the vaulting and tie the bunches on with osier withes, so as to clip them even afterwards with shears.
Let the distance from one circle to another be half a braccia; and the juniper [sprigs] must lie top downwards, beginning from below.
Round this column tie four poles to which willows about as thick as a finger must be nailed and then begin from the bottom and work upwards with bunches of juniper sprigs, the tops downwards, that is upside down. [Footnote: See Pl. CII, No. 3. The words here given as the title line, lines 1—4, are the last in the original MS.—Lines 5—16 are written under fig. 4.]
