The world was ordered, the sun ran its course – but the shore lay empty. Then three gods found on the sea-strand two pieces of driftwood and made from them the first human pair: Ask and Embla. From them, says the Edda, we all descend.
Ask (‘ash’) and Embla (probably ‘elm’, or a word for a vine) were at first lifeless logs without fate. Only the gifts of the gods made them human.
According to the Völuspá, three Æsir came to the shore: Odin, Hönir and Lodurr (in Snorri: Odin, Vili and Vé). They found Ask and Embla ‘without breath, without fate’. Odin gave them önd – breath, the spirit of life; Hönir gave óðr – mind and motion; Lodurr gave lá and litr góðr – warmth, blood and blooming hue. So from dead wood came a living human, at home in Midgard.
“Soul they had not, sense they had not, / heat nor motion, nor goodly hue; / soul gave Othin, sense gave Hönir, / heat gave Lothur and goodly hue.”Völuspá 18, translation after Henry Adams Bellows (public domain)
