Vessel linework

[Jorge_Stolfi]

Don't know if this will lead to "later" or just "different".

I conjectured that Pharma-1 was created after Pharma-2 because there seems to be an evolution of the style of jars, from simple cylindrical ones in most of Pharma-2 to the more elaborate ones in Pharma-1; and the evolution seems to have started on the last two pages of Pharma-2 -- specifically on the verso of folio f102, the last of Quire 19.

All the best, --stolfi
