later in the year, to follow Theo's recommendation that he study with the Dutch artist Willem Roelofs, who persuaded him – in spite of his dislike of formal schools of art – to attend the Académie Royale des Beaux-Arts. He registered at the Académie in November 1880, where he studied anatomy and the standard rules of modelling and perspective. Etten, Drenthe and The Hague Van Gogh returned to Etten in April 1881 for an extended stay with his parents. He continued to draw, often using his neighbours as subjects. In August 1881, his recently widowed cousin, Cornelia "Kee" Vos-Stricker, daughter of his mother's older sister Willemina and Johannes Stricker, arrived for a visit.

Mauve invited him to return in a few months and suggested he spend the intervening time working in charcoal and pastels; Van Gogh returned to Etten and followed this advice. Late in November 1881, Van Gogh wrote a letter to Johannes Stricker, one which he described to Theo as an attack. Within days he left for Amsterdam. Kee would not meet him, and her parents wrote that his "persistence is disgusting". In despair, he held his left hand in the flame of a lamp, with the words: "Let me see her for as long as I can keep my hand in the flame." He did not recall the event well, but later assumed that his uncle had blown out the flame. Kee's father made it clear that her refusal should be heeded and that the two would not marry, largely because of Van Gogh's inability to support himself. Mauve took Van Gogh on as a student and introduced him to watercolour, which he worked on for the next month before returning home for Christmas. He quarrelled with his father, refusing to attend church, and left for The Hague. In January 1882, Mauve introduced him to painting in oil and lent him money to set up a
