Note 1858 — BOOK XXVI.
Lewis Evans translation
Lira is properly "the ridge thrown up between two furrows." Hence lirare, "to plow or harrow in the seed." [In Juv., Sat. xiii., 65, some read "liranti sub aratro."] Delirare, therefore, is "to go out of the right furrow." Hence, "to deviate from the straight course, to go wrong, or deranged." Hor., i., Ep. xii., 20, "Quidquid delirant reges plectuntur Achivi."
