Hello there! We know terribly little about Carthaginian religion besides what the major gods and goddesses represented, and that's mainly because Greek and Roman sources use native terminology to describe Punic deities (e.g., Zeus-Saturn-Baal Hammon, Heracles-Hercules-Melqart). An even wider range of minor (e.g., Arish) and foreign (e.g., Isis) deities can be found in inscriptions and theophoric personal names. No Carthaginian religious texts have survived, unfortunately. You may nevertheless be interested in another post I wrote on the worship of Baal. Please let me know if you any further questions! :)
