Diamond-point engraving involved incising the surface of a glass with a diamond-tip or steel burin. It was a simple technique, often practised by skilled amateur decorators, likely introduced into the Netherlands by Venetian craftsmen and which reached high levels of refinement in the Dutch Republic during the mid seventeenth century. Glasses were inscribed with both scrolling calligraphic text and pictorial imagery. Rotterdam craftsman Willem Mooleyser became a particularly skilled and distinctive engraver. Many works from the time are designated as in the manner of Mooleyser, but this bottle may be attributed with some confidence to Mooleyser himself.
