The vesna or vesnas were mythological female characters associated with youth and springtime in early Slavic mythology, particularly within Croatia, Serbia and Slovenia. Along with her male companion Vesnik, she was associated with rituals conducted in rural areas during springtime.
Beautiful women called "vesnas" lived in palaces atop mountains where they discussed the fate of crops and of human inhabitants. A magical circle around their palaces kept them from leaving the mountain top except during the month of February, when they would travel in wooden carts down to the valley below. Only certain people were capable of hearing them singing. People who snuck up to their mountain palaces might learn their fates, but risked an unpleasant end if they were caught by the vesnas.
