The roemer was a type of drinking glass that originated in Germany during the fifteenth century, comprising a conical foot, a wide, hollow shaft and a large bowl. The shaft and bowl were generally blown as one form and distinguished, visually, by an applied glass trail around the juncture. The shafts of roemers were also embellished with applied prunts, or discs of glass with raised bumps, that were both decorative and practical in allowing a firm grip. Roemers were generally green in colour, the tint reflecting iron impurities in the glass body. They were imported into the Netherlands in the thousands during the seventeenth century, where they were popular for white wine and often appeared in still-life paintings.
