Elate (mythology)
In Greek mythology, Elate () is a minor figure, the sister of the two Aloadae giants. Family 
As sister to the Aloadae, Elate was probably the daughter of Iphimedeia by either Aloeus or Poseidon, the god of the sea. Mythology 
Elate was big in size, as big as her enormous brothers. When they died after trying to wage war against the heavens, she mourned them so much she was changed into a fir tree. She kept however her great size in her new life, hence the ancient Greek expression "a silver-fir tree big as heaven." Her sister, Platanus, had a similar fate. See also
