Piirissaar, born from Kalevipoeg's pillow

Worn out, Kalevipoeg came to the shore of Lake Peipus and wanted something under his head. He carried three haystacks together and lay down. Soon he snored so loudly that villagers thought thunder was playing far away. The sorcerer of Peipus crept up, laid seven kinds of sleeping herbs by the giant's nose and pulled the hay from under his head, armful by armful, into the lake. Kalevipoeg slept for seven weeks. When he woke, his pillow was gone and the thief long fled. He threw the herbs after the hay. Year by year the waves heaped sand and rubbish on the floating hay, and so Piirissaar island grew.
