   • Radiography (X-ray photography): A historical term for the process of taking X-ray photographs, also spelled "skiagraphy."
   • Vertical section (architecture): In architecture, "sciagraphy" denotes a vertical cross-section of a building, showing internal structure.
   • Measurement of shadows (astronomy): In astronomy, "sciagraphy" is the measurement of shadows, especially of the sun, to determine time.

Usage Examples

• Architecture:
  • The architect produced a sciagraphy of the house to show the layout of floors and rooms. (A vertical cross-section drawing.)
• Astronomy:
  • Ancient astronomers relied on sciagraphy to calculate the time of day from the sun's shadow length. (They measured shadows for timekeeping.)

Advanced Usage

• "sciagraphy of a building": a vertical section drawing in architecture.
