Lord Rokeby refused to have a fire in his house even in the coldest weather. He grew an immense and bizarre looking beard, that was not in fashion at any times Thick beard stuck out under his arms and could be seen from behind. A couple of years later he built a swimming pool under glass which was heated only by the sun. There he spent most of the time, preferably alone.

In the end his neighbors and other locals became scared of him because his increased isolation gave birth to all kind of rumors. One of them was that Lord Rokeby became a cannibal and ate only raw meat. But, in fact he rarely ate meat at all and refused to see any doctors. He did not go to church either because he complained that sermons were boring and that he preferred to worship God at natural altar of the earth, sea and the sky.

He never married. On the extremely rare occasions when Matthew had to accept visitors he tried to get rid of them fast by entertaining them with lengthy boring poems. All his aristocratic relatives were ashamed of him, especially during his occasional visits to court. His presence usually gathered big crowds of people on the streets who thought that Matthew was an ambassador of Turkey - because of his unusual appearance.
