Square's Brother

Square's Brother, the Chief Clerk of the High Council, is a perfectly symmetrical Square whose loyalty to his office and affection for his brother coexist with the secrecy enforced by the Council. He witnesses Sphere's appearance, is imprisoned for life to prevent disclosure, and later visits Square regularly; yet even seven years of explanations leave him unconvinced that the Third Dimension or Sphere exists.

Identity and Position

At the millennial meeting of the High Council, Square's Brother reads the minutes as its Chief Clerk. Square recognizes him as a perfectly symmetrical Square, a description that marks him as a regular member of his class and distinguishes him from the irregular figures targeted by the Council's recorded orders. His position gives him access to the Council's proceedings, but not protection from its authority.

Witness to the Council's Secret

Square's Brother is present when Sphere enters the Council chamber and proclaims the existence of a land of Three Dimensions. The President later reveals to the junior Circles that the secret archives record similar appearances at the previous two millennial commencements. The Council orders the guards to arrest the policemen who witnessed the incident and gag them; Square's Brother, the clerk who has read the records, is also made subject to the secrecy that surrounds the repeated events.

Before leaving, the President expresses regret that precedent and the need for secrecy require Square's Brother's perpetual imprisonment. He nevertheless says that his life will be spared unless he mentions what happened that day. The sentence thus protects the Council's secret while leaving him alive under an explicit condition of silence.

Imprisonment and Fraternal Visits

Square's Brother is imprisoned before Square, and the brothers are eventually allowed occasional visits. Seven years after Square's own sentence, those interviews have become weekly, and Square describes his brother as just, sensible, cheerful, and not without fraternal affection. Their meetings are one of Square's few remaining forms of companionship, since he is otherwise confined to the company of his jailers.

The visits also carry a recurring disappointment. Square repeats the account of his part in Sphere's manifestation, describes the phenomena of Spaceland, and offers arguments for solid things by analogy. Although Square's Brother witnessed Sphere's changing sections and heard the explanation in the Council chamber, he still does not grasp the Third Dimension and openly disbelieves in Sphere's existence. His proximity to the revelation therefore does not make him a convert: even an eyewitness and a brother cannot be persuaded by Square's accounts.

Narrative Significance

Square's Brother binds the Council's concealed history to Square's later imprisonment. As clerk, he reads records showing that Sphere's appearances have happened at two earlier millennial beginnings; as witness, he sees the new appearance; as prisoner, he is prevented from publicly carrying that knowledge forward. His fate makes secrecy an institutional practice rather than a momentary reaction.

His continued disbelief also sharpens the contrast between witnessing an event and understanding its meaning. The weekly conversations give Square a listener, but not the convert he hopes to make, leaving him with no converts and little prospect of spreading his account in Flatland. Square's Brother remains at once a source of fraternal companionship and a measure of how firmly the limits of his world resist even direct testimony.
