Near Crissa, but established later, was a seaport named Cirrha. In course of time the seaport town of Cirrha increased at the expense of Crissa; and the sanctuary of Pytho grew into the town of Delphi, which claimed to be independent of Crissa. Thus Crissa declined, as Cirrha and Delphi rose in importance. Cirrha was destroyed in the First Sacred War; but the fate of Crissa is uncertain. It is not improbable that Crissa had sunk into insignificance before this war, and that some of its inhabitants had settled at Delphi, and others at Cirrha.
