Evolución de los soportes documentales para la lectura y la escritura

Main ideas and concepts (evolution of documentary supports for reading/writing)

Core problem driving technological change

• Humanity needed to fix and preserve acquired knowledge so it could transcend space and time, moving beyond:
  • oral transmission
  • human memory

Early preservation methods

• Oral transmission
  • Knowledge lived only in the memory of those who heard it.
• Cave imagery / proto-writing
  • Visual marks used to “record” knowledge.
  • Example cited: cave symbols dating back ~35,000 years.

First “books” and physical media

• Mesopotamian books (Sumerians)
  • Often described as the first book in history.
  • Written over 3,500 years ago on clay tablets (about 40 cm).
• Papyrus
  • Mentioned as an early document format that included illustrations.
  • Stored and protected by being rolled, then kept in:
    • clay tubs
    • wooden boxes
    • leather cases
  • Though expensive and fragile, papyrus remained in use for about 3,000 years.

Role of the Hispanic Digital Library / National Library of Spain

• The talk highlights that major historical documents are:
  • digitized
  • made available for study
• Several notable manuscripts and works are emphasized, especially from Spain’s key libraries, notably the National Library of Spain.

Major transition: papyrus → parchment → codex

• Parchment
  • Appears in the 1st millennium BC as a substitute for papyrus.
  • Made from calf, sheep, or goat skins
  • Tanned with lime
• Codex
  • Enabled by parchment.
  • A predecessor of the modern book:
    • built from multiple folded and sewn parchment leaves
    • designed to mimic the shape of ancient clay tablets
  • “Codex” is described as a common term for handwritten books from the pre-printing period.

Illuminated manuscripts and medieval literary culture

• Christian monasteries acted as:
  • centers of literary production
  • the birthplace of illuminated manuscripts
• These books were:
  • handwritten
  • decorated with gold, silver, and bright colors
  • filled with ornamented capital letters and small illustrations

Paper and printing accelerate mass preservation

• Paper
  • Presented as decisive.
  • Origin and spread:
    • invented in China, alongside printing
    • plant-based production (primarily cellulose and plant materials)
    • introduced to Spain by Arabs in the 11th century
    • first Spanish references cited for 1154
• Bible of the Poor (Biblia Pauperum)
  • Identified as an incunabulum (early printed book)
  • Dated to a 15th-century style:
    • illustrations and simple phrases created using woodblock-based printing

Printing revolution (movable type)

• Printing from the 1450s caused a radical change.
• Johannes Gutenberg’s method
  • created movable lead type
  • integrated it into a modified grape press
  • produced a primitive printing press
  • movable elements formed the page impression via ink, using the reverse side of letters
• Early output
  • One of the first works: a Gothic-type Bible
  • Two columns
  • 42 lines per page
• Incunabula definition
  • Books printed with movable type before January 1, 1501

From early modern to modern printing technologies

• 15th–16th centuries
  • influence from certain incunabula is mentioned (example: a natural geology work reconciling reason and faith)
• Industrial Revolution (19th century)
  • emergence of modern techniques such as lithography
  • followed shortly after by the rotary press
• Early 20th century
  • printing reached its peak with offset printing
  • identified as the method used today
