PO-MO celebrates the Stonemason this summer, taking inspiration from small carved symbols found among the stone walls of the mysterious Vienna Cathedral. The Stonemasons’ created complex templates that allowed them to create a unique personal mark to help distinguish one masons work from another. The Stonemason would carve this mark into stone, these marks were called Mutterfiguren. The ‘Mutterfiguren’ symbols are created from the Steinmetz-Grund, a very secret geometric law, on-which the stonemasons constructed and designed buildings. The Steinmertz-Grund, roughly meaning ‘stone cutter’–‘logic’, dates back to the twelfth century. The graphics used among the Steinmertz-Grund look sweet on these most Post-Modern Tees.
