In Jain literature, Matang is described as the son of Vinami, and Vinami is said to be a descendant of Rishabhanatha (the first Tirthankar). Matang is often treated as the founder of the Matang lineage or caste in ancient Jain accounts, and the name is connected with various Matang-associated figures in Jain stories (e.g., a Matang Yaksha and references to Matang in the lineages of Tirthankaras).

Different Jain traditions give slightly different details:

• Digambara and Śvetāmbara traditions sometimes differ on exactly which figures are Matang and how the Matang lineage relates to specific Tirthankaras or yakshas.
• For example, some traditions associate Matang with Suparśvanath (the 7th Tirthankara) and with Matang as a Yaksha or attendant figure in certain narratives; others emphasize Matang primarily as Vinami’s son and as the progenitor of the Matang line.

If you’d like, I can summarize the dharma-meaning of these references from canonical Jain narratives and note the exact points where Digambara and Śvetāmbara texts diverge.
