 At the end of the nave is a Jacobean gallery with four oak pillars about 9 feet ( 3 m ) tall . It dates from 1637 and there are sixteen figures carved on it . These figures are typical of the Stuart period and represent the twelve apostles and the Four Evangelists ( meaning that Matthew and Mark appear twice ) . At the centre are Saint Andrew ( with an X cross ) , Saint Peter ( with a key ) and Saint John ( with the chalice ) .
