Surprisingly, the Royal Scriptorium in Constantinople was still churning out purple MSS as late as the 1500s:
|Tetraevangelion. Miniature of St Mark|
Gold on purple parchment. 9th century
The National Library of Russia site tells us:
Codex Petropolitanus Purpureus, designated by N or 022, is shown below, in a much crappier photo:
"Nicholas I was given a precious eleventh-century purple Gospel which had once belonged to the Christian community of Gumushane (also in Asia Minor). This volume written in gold and silver and adorned with miniatures was produced in the imperial Byzantine scriptorium. Another work from the same source is the Codex Petropolitanus, a sixth-century purple Gospel which Nicholas II bought from the village of Sarmisahly with the assistance of the Russian Archaeological Institute in Constantinople."
|Petropolitanus (6th cent.)|
