Note 193 — II 1325-1521
Reading edition
His modern editor, José Ignacio Roquette (1801-70), comments (p. 37) on the passage he bem de lavrar e criarem as a great grammatical discordancia and erro, but it is by no means certain that King Duarte did not omit one of the personal infinitives deliberately, for the sake of euphony, as the -mente is omitted in the case of two or more adverbs.
