Fidelity

Palazzo Ducale in Venice: capital # 28 in the porch, featuring Virtues and vices — In fidelitate nulli gero (Fidelity)

Fidelity is the quality of faithfulness or loyalty. Its original meaning regarded duty in a broader sense than the related concept of fealty. Both derive from the Latin word fidēlis, meaning "faithful or loyal". In the City of London financial markets it has traditionally been used in the sense encompassed in the motto "my word is my bond".
