# 094 Visualizing the evolution of pharma jars

INTRODUCTION

  The Pharma section is divided int two parts
  
    Pharma-1 pha.1 f88r .. f89v1
    Pharma-2 pha.2 f99r .. f102v1
    
  The jars in the margins of those pages suggest 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.
  
  This note aims to create a single image showing the evolution of 
  the jars in that sequence.
