Result
One day Geralt got an unusual proposition. A portrait artist, inspired and delighted by the witcher's singular appearance, asked if he would pose for a painting. Largely open to the varied experiences life offers, the witcher agreed to model for the painter. Though he later claimed he was driven primarily by a desire to support the arts (an impulse laudable in and of itself!), I suspect plain old vanity might also have come into play. The witcher and the artist set off together for the countryside, where the beautiful landscape was to serve as the backdrop for the portrait.
