Note 56 — CANTO THE FIRST.
Reading edition
[If, as stanza xliii. of this canto (added in 1811) intimates, Byron passed through "Albuera's plain" on his way from Lisbon to Seville, he must have crossed the frontier at a point between Elvas and Badajoz. In that case the "silver streamlet" may be identified as the Caia. Beckford remarks on "the rivulet which separates the two kingdoms" (Italy, etc., 1834, p. 291).]
