touches on the dark side of your outline, and observe the variety of touch on the
brick and stone work.
Plate XVIII. is introduced in connection with the preceding drawing, because it
represents the interior of Lollard Tower, in Lambeth Palace. This building was the
prison of the early reformers, who were converted from the errors that disgrace the
church of Rome, by the arguments and writings of Wickliff; those converts were in
derision called Lollards, and the scene of their confinement retains the name. It is a
small dark room, measuring only twelve feet by nine, formed of thick oak planks,
studded with iron; the rings and staples to which the unfortunate prisoners were
chained, still remain.
This room is an excellent subject for shewing the lines running on all sides to one
point of sight; this point, by applying your rule, you will find in a large spot upon
the edge of the board in which the rings are inserted, near the centre of the picture;
the double line in the margin shews the horizontal line.
