I am the mother by Zeus of britomartis a certain goddess?

In Greek mythology, Britomartis is often associated with hunting and is considered a goddess of the hunt and the moon. However, she is not explicitly listed as a daughter of Zeus, but rather is sometimes described as a daughter of the Cretan King Minos or as a manifestation of Artemis. If you are referring to the broader context of Zeus's offspring, he fathered many gods and goddesses, but Britomartis's origins are less directly tied to him.
