Note 895 — Chapter XII · THE SWORD IN ANCIENT ROME; THE LEGION AND THE GLADIATOR.
Reading edition
The word seems to be a congener of Sahs, Sax, or Seax, the weapon supposed to have named the Saxons. It was either straight or curved, the main object being to fit it closely to the body or under the armpits. Hence it was a favourite with the Sicarius (Ital. sicario), the Assassin. Gregory of Tours has (ix. 19) ‘Caput sicharii siccâ dividit.’ A fanciful derivation of Sicily is from sica, because Cronos threw one away at Drepanum. From the diminutive form Sicula and Silicicula comes the English ‘sickle.’
