About this source

What it is

This is a scan of the handwritten signature of Constantine XI Palaiologos, written in cursive Greek with flourishes, as used in his role as Emperor of the Romans.

Why it matters

A signature is one of the most personal traces a historical figure can leave behind, showing the actual hand of the person rather than an artist's interpretation. This signature reflects Byzantine chancery traditions, the formal writing practices used in imperial documents, and connects directly to Constantine XI as the man who ruled during the empire's final years.

Look closer

  • What does the style of the handwriting—its flourishes and strokes—suggest about the formality of imperial documents?
  • Why might emperors develop a distinctive, hard-to-copy signature style?
  • How is a signature different from a portrait as evidence about a person?
