What is it that is making fire so comforting?
Ephraim thought about it several times already in his life as he studied mythology.
Prometheus.
The titan who stole fire from Hestia's hearth, or in some versions, from Zeus, and gave it to the mortals. He was the titan who had created the humans from clay and had taken pity to his creation thereby giving them the fire. For his crimes, Prometheus was castigated by Zeus who bound him with shackles while sending an eagle to eat Prometheus' immortal liver every day—which actually grew back every night. Several years later, Heracles, a Greek hero, with the odd permission of Zeus (the god who basically did all the wreckage), killed the eagle and freed Prometheus from the torment he received.
