Nabu later became one of the principal gods in Assyria. He even surpassed Marduk in popularity, perhaps because of Marduk's association with Babylonia, which was Assyria's rival. The Assyrians addressed many prayers and inscriptions to Nabu and named children after him. As god of writing and scribes, Nabu was the keeper of the Tablets of Destiny, in which the fate of humankind was recorded. In addition, he was sometimes worshiped as a fertility god and as a god of water.
