Constructing "Geoffrey Chaucer" (1598)

Thomas Speght's edition of Chaucer's collected works:  title page, Title page comparison, Mirrour for Magistrates 1574 vs. Speght Chaucer 1598,  Chaucer portrait page owner signature, "Knight's Tale" Fol. 1, "To the Reader" with initial short "s," Beaumont letter with patch recto. 

Garrett Library Chaucer Stow Edition (1561) Manuscript Notes: at the end of this first "collected works" of Chaucer, just before works by John Lydgate and other poets are added by the printer as an "bonus," a former owner has written something in a C16 manuscript hand.  It reproduces something found on an architectural monument in Westminster Abbey and printed in all Renaissance editions of Chaucer from 1601 onward.  Apparently the Stow edition's owner believed this inscription was necessary to complete the collected works of Chaucer.
