Kathleen Schlesinger and Alfred J. Hipkins, 1911 Encyclopædia Britannica (1911)
“ The confusion doubtless arose from the fact that from the 11th century cithara is glossed hearpan in Anglo-Saxon MSS., a word which, like citharisare in medieval Latin, referred to plucking or twanging of strings in contradistinction to those instruments vibrated by means of the bow. In Irish of the 8th and 9th centuries (Zeuss) cithara is always glossed by “crot.” The modern Welsh “crwth” is not a harp but a “rotta” (see Crowd) . An old Welsh harp, not triple strung, exists, which bears a great resemblance to the Irish harp in neck, soundboard and soundholes. ”
