After arrest Oscar Wilde was moved to Pentonville Prison, where the "hard labour" to which he had been sentenced consisted of many hours of walking a treadmill and picking oakum (separating the fibres in scraps of old navy ropes), and where prisoners were allowed to read only the Bible and The Pilgrim's Progress. Prisoners were not allowed to speak to each other, and, when out of their cells, were required to wear a cap with a thick veil so they would not be recognised by other prisoners.
