As a geometrical symbol, the monad or single point represents unity and corresponds to the fundamental unit from which all forms and numbers originate 1. When early humanity sought to depict the concept of a single, unified deity, it rendered that unity as a point 2.

In Masonic teaching, numbers do not possess supernatural or magical virtues; rather, they serve as symbols for sacred objects or ideas 1. While Albert Mackey notes that the primary symbolic numbers emphasized in Craft Masonry are odd numbers such as three, five, seven, and nine, the monad retained a role in historical lecture revisions—such as Doctor Hemming's 1813 explanation of the Pythagorean triangle—where the single point signifies unity and the Active Principle or Creator 1.

Geometrically represented as a single point, the number one signifies unity and serves as the fundamental principle from which all combinations of form and number are generated 1. Early human thought, seeking to depict the concept of a single, unified deity rather than a collection of localized spirits, visually rendered that idea of divine unity as a central point 2.

Within the lectures revised by Doctor Hemming in 1813, this symbol is elucidated through the Pythagorean triangle or tetractys 1. In this system, ten points are arranged to form one great equilateral triangle divided into nine smaller ones 1. The first point, representing unity, is denominated the monad; it corresponds to the geometric point, serving as the originating principle of all geometric forms and numerical series 1. In the broader Pythagorean doctrine that parallels this Masonic instruction, the single point symbolizes the Active Principle or Creator 1.

Masonic instruction uses numbers strictly as symbols for sacred objects or holy thoughts, maintaining a firm distinction between symbolic numbers and the occult theories of numerology 1. The operative and speculative traditions relied on sound geometric principles rather than magical properties 1. Within this framework, the number one stands not as an isolated quantity, but as the emblem of undivided unity, divine cause, and the geometric source from which structured creation proceeds 121.

In Masonic teaching, numbers possess no supernatural or magical virtues; rather, they serve strictly as symbols representing sacred objects or ideas 1. Geometrically represented as a single point or monad, the number one signifies unity 21.

When early humanity conceived that the universe was governed not by localized spirits but by a single God, it visually depicted that central concept of divine unity as a single point 2. This geometric point thus stands as a primary symbol for the unity and oneness of the Creator 21.

The symbol is further elaborated through the Pythagorean tetractys, which Doctor Hemming incorporated into his 1813 revision of the English lectures 1. In this system, ten points are arranged to form one large equilateral triangle containing nine smaller ones 1. The initial single point—denominated the monad—represents the Active Principle or Creator 1. Just as a point in geometry serves as the fundamental unit from which all shapes are derived, the monad acts as the primary principle from which all combinations of number and form are generated 1.
