Operative deceits occurred from “the substitution of cast or machine work for that of the hand.” However, there are sometimes exceptions. Surface deceits occur when one material is painted to look like another. Structural deceits occurred in several forms: members such as columns, that appear to serve a structural role but do not the concealment of primary structural members the use of structural members that do not convey or contradict the vertical or horizontal forces at work and the use of iron as a reinforcement for masonry. Ruskin articulated three types of deceits: structural deceits, surface deceits and operative deceits. In other words, an honest display of the construction process and structure. The second lamp is the lamp of truth that focuses on the truthfulness of materials.

However, he is making an argument that sacrifice has value in itself. Nowadays, we desire to produce the largest results at the least cost. The lamp of sacrifice suggests offering precious things merely because they are precious, not because they are useful or necessary which is the opposite idea of the prevalent feeling of modern times. Ruskin arranges proper architecture under five heads: devotional, memorial, civil, military, and domestic. Ruskin describes architecture as the art that enhances and adorns buildings created by man, so that the sight of them contributes to his mental health, power and pleasure. In other words, whatever we do, we must do well, as if we were trying to please God. The first lamp is the lamp of sacrifice that is portrayed as the dedication of a man’s craft to God. During this essay, I will discuss these seven lamps of sacrifice, truth, power, beauty, life, memory, and obedience.

The seven lamps of architecture presented by John Ruskin are meant to represent the demands that architecture must meet in order to be considered good architecture. However, I was interested in learning more about these 7 lamps.

Although we mentioned the seven lamps when we discussed this chapter during class we mainly focused on “The Lamp of Truth”, mostly because we were discussing the questions of truth that rose during the 19 th century with new technological advancements. It was during that time that we read John Ruskin’s original text “The Lamp of Truth”. During the third chapter of the book “Introducing Architectural Theory” we discussed the themes of honesty and deception.
