Punctum (Punctuation Mark)

The image consists of a single, small, solid black glyph representing a punctum from medieval musical notation. It is roughly oval-shaped with a slight tapering or downward-curving stroke, characteristic of neumatic notation used in Gregorian chant manuscripts. The edges are slightly irregular, suggesting a hand-drawn quill or reed pen application on a porous surface.

The punctum is one of the fundamental units of neumatic notation, used in the Western liturgical tradition to indicate a single pitch. Such marks were essential for the transmission of monophonic plainchant before the development of staff notation.
