Virgo - Star in the hand?

[Koen G]

I went quite deep in researching this fashion. It is sometimes referred to as "international" or "courtly" style, exactly because it was fashionable at all trendy courts of Europe. I first also thought the MS was 13th century because of the Roman numeral, but when I saw the baggy sleeves on one of the figures I knew it had to be ca. 1400-1430.

So in short, this fashion does not help us to pin down a location, but it is very good at pinning down time to a few decades (and indeed is used as such by professionals).
