f17r

[julian]

I have a multi-lingual take on this, which I developed after a glass of wine last night. Today I thought "I bet that f17r marginalia has been covered on the Ninja", and wasn't disappointed!



This looks like (if you squint hard enough): "malhar allar lut3 hest vitellum" ... with maybe some faint characters afterwards.  

1. malhar - (Portugese) meaning "strike" or "thresh"
   
   
2. allar - (Icelandic) meaning "all"
   
   
3. lut3 - (Latin) Luteum meaning "yellow". The short line above the "t3" is a macron, and scribes in medieval times usually used it to indicate an abbreviation, most commonly a missing "m" or "n". The "3" itself can mean a missing "ue". 
   
   
4. hest - (Latin) meaning "best"
   
   
5. vitellum - (Latin) meaning "yolk"
   

The obvious interpretation is as a puzzling multi-language instruction to "beat all your best yellow yolks" - perhaps in order to make a desert using the plant depicted on the same folio?
