At a glance
“Incredulity of Thomas” is a major narrative subject. Attribute: spear or builder’s square. Mission to India in later legend.
Incredulity composition
Christ guides Thomas’s finger into the side wound; apostles cluster in disbelief-turned-faith. Title panels often name the scene—use that before guessing attributes.
Spear and square
Tradition of martyrdom by spear in India supplies standalone attribute; builder’s square references earlier carpenter association and church-building legend.
Mission to India
Later legend and Syro-Malabar tradition strengthened Thomas’s Asian mission iconography—explaining occasional exotic dress in missionary portraits outside standard apostolic robes.
