Throughout the Kumarbi Cycle, beside Teshub the storm-king walks his brother Tashmishu — the steady second figure, who counsels Teshub when Teshub is about to act rashly, who supports him in battle when his strength flags, who serves as the brother-vizier of the storm-king's house. He is, in his quieter way, one of the more fully drawn supporting figures in Hurrian-Hittite mythology.
It was Tashmishu who, in the Song of Ullikummi, climbed the high mountain with Teshub and looked upon the rising stone giant; it was Tashmishu who stood by Teshub through the despair that followed; it was Tashmishu who, when Ea brought the saw and the giant fell, helped his brother to recover his throne. He has no great solo myth attached to him, no separate cult of grandeur. But within the narrative, he is the figure whose presence makes Teshub's heroism possible by giving Teshub a brother to whom he need not pretend invulnerability.
