Note 923 — XXIII. THE HERESIES.
Reading edition
La Nobla Leyczon, 408-13.—There has been considerable discussion as to the date of this work. It appears to me to bear the mark of more than one period, or, at least, of successive recensions. Internal evidence shows the beginning to have been written about the year 1100, while the later portion, commencing about l. 345, seems to have been composed subsequently to the persecutions of the early part of the 13th century.
