According to Houbraken he won a lucrative commission from the Delft vroedschap to repair his grandfather's schutterstuk after the Delft Explosion in 1654 damaged it. This showed not only the respect the young man had for his grandfather, but also the value that the Delft council placed on their schutterstuk by him. According to the RKD his wedding portrait and the pendant of his wife were drawn from (now lost) paintings and are in the possession of the Leiden Library. The schutterstuk that Arnold Houbraken mentioned is in the Delft city hall, in the room reserved for weddings.
