Since 1573, the Utrecht militia was divided into eight companies, all carrying interesting names such as Papenvaandel (pape banner), Handvoetboog (hand-foot bow) or ’t Fortuyn (the fortune). The militia companies also had a social function, giving festive banquets with vast amounts to eat and drink. Their actual role of defence started losing priority, until after 1780, when the Patriots demanded that gun practice was to be taken seriously again. The restored militia companies became the core of the revolutionary movement. This engraved glass dates back to this period. The unknown engraver has portrayed goddess Fortuna (symbol of the company) on the one side and the Utrecht city arms on the other.
