Note 530 — Chapter I · FLAX.
Reading edition
The origin of Stuppa, the Latin term, was from its use in stopping chinks (stopfer, German). It was either of hemp or flax.
“Stuppa cannabi est sive lini. Hæc secundum antiquam orthographiam stuppa (stipa?) dicitur, quod ex eâ rimæ navium stipentur: unde et stipatores dicuntur, qui in vallibus eam componunt.” Isid. Hisp. Orig. xix. 27.
