It was doubtless the fame the Diest plans earned for him which decided the Louvainers to commission our mason to rebuild their church, and in the following year to name him City Architect. From this time until his death Van Vorst must have been a busy man. His civic appointment was no sinecure; he had not only to direct and supervise whatever building operations the city fathers had in hand, but also to purchase the building materials, which meant frequent journeys on horseback to the quarries at Afflighem and Roteslaer; the work at Saint Peter's, too, must have occupied much of his time, and we may be sure that he was often at Diest to see after the building operations there. Yet somehow or other, like most busy men, he found time for recreation. At times he seems to have amused himself by making models of divers architectural monuments, for we know that the city magistrates were so delighted with some of these productions that, on the 11th of December, 1434, they voted him a _gratification_ of 13 golden florins. Again we learn from the city archives that, on the 29th of May 1425, he took part in the Corpus Christi procession, marching at the head of his guild, and we may be quite sure, though the fact is not recorded, that when the religious ceremonies were over Meester Plysis and his brother masons withdrew to their wonted tavern, and there regaled themselves, not on the every-day malt liquor--though Louvain, even in those days, was famous for its ale--but, as was usual on festive occasions, with a bottle or so of the best Rhenish. Yet another little intimate scene which some entries in the city records have enabled us to reconstruct. It took place on the 20th of May 1439, when the great architect, for the last time, received the congratulations of his comrades. Less than four months later he went the way of all flesh.
