Which Tirthankara's symbol is a crescent moon?

Chandraprabha’s symbol is the crescent moon, shown beneath his image in Jain artistic tradition.

Chandraprabha was the eighth Tirthankara of the present Jain time cycle. His name combines chandra, meaning “moon,” with prabha, meaning “radiance” or “light,” making the lunar emblem especially fitting. Jain images commonly portray him seated in meditation or standing in the kayotsarga posture, with the crescent moon serving as his identifying mark.

Tirthankara images are deliberately similar in their calm posture and meditative expression. Their individual emblems are therefore important for recognizing them. The crescent moon distinguishes Chandraprabha from neighbouring Tirthankaras such as Suparshvanatha, whose symbol is a swastika, and Pushpadanta, whose emblem is a crocodile.

Chandraprabha is traditionally associated with the Naga tree, the Yaksha Vijaya or Shyama in different Jain traditions, and the goddess Jwalamalini or Bhrikuti. As with other Tirthankaras, the emblem is an iconographic identifier rather than a claim that the figure is a deity who controls the moon.
