Today marks the 500th anniversary of Scottish printing, and the National Library is showing off one of its greatest treasures for the occasion: the only known copy of the earliest dated book printed in Scotland.
The colophon to John Lydgate's poem known as the Complaint of the Black Knight reads "[Impre[n]tit in the south gait of Edinburgh : Be Walter chepman and Androw myllar, the fourth day of ap[r]il the yhere of god .M.CCCCC. and viii. yheris]" ... that is "Printed in the South Gate of Edinburgh: by Walter Chepman and Andrew Myllar, 4 April 1508." You can virtually-page through the Complaint here (images and transcriptions).
Lydgate's poem is bound together with the eight other known Chepman/Myllar books as well as two items by other printers.
