Ernest Weekley, The Romance of Words (4th ed.)
“ Between the basnet and these reigned the salet or salade, on which Jack Cade puns execrably—"Wherefore, on a brick wall have I climbed into this garden, to see if I can eat grass, or pick a sallet another while, which is not amiss to cool a man's stomach this hot weather. And I think this word sallet was born to do me good, for many a time, but for a sallet, my brain-pan had been cleft with a brown-bill." (2 Henry VI., iv. 10.) It comes, through Fr. salade, from Ital. celata, "a scull, a helmet, a morion, a sallat, a headpiece" (Florio) . ”
