It was a good week before the mysterious deity got a response. The god was still a mystery because Re didn't recognize the writing used to display his name. Or her name, he often reminded himself. There was no way of knowing, at this point.
What he did understand from the messages he'd received was that this deity was night. Or the night sky. Or darkness. Something along those lines. He hadn't realized that at first when he'd depicted the night slinking away before his light. But the portrayal of the raven had made that clear. Which left him with a slight dilemma on how to reply.
Nighttime held very real fear in Egypt, for the mortals as well as the gods. But he didn't want to actually offend whoever this humorous deity was. He was beginning to enjoy their "conversations" and looked forward to having more. Which was why he took his time, sketching out what he wanted to say, making changes here and there, before attempting to put it out there to be seen.
When he thought he was satisfied, Re took a considerable amount of the black earth along the River to aid his artwork, along with some red ochre, and began to draw. Even with his plan already in mind, it took most of the day to complete, but when he was done he was fairly satisfied with the results and hoped the scene was conveyed well enough to be easily understood.
The first scene depicted himself, the sun disk prominently displayed upon his head, below the line that separated the curved earth and the underworld. There, he stood in his boat, fighting a mighty snake and many smaller snakes. On the curve of the earth, dangerous creatures such as lions and hippos were gathered behind a flock of people praying for the sun's return and triumph.
The next was similar to the last one the other god had seen, in that the sun had come over the horizon and the people were celebrating. This time, the sun was clearly the falcon, a wing wiping his brow in relief.
The next two were meant as the real message. While Re knew what night meant in his land, he didn't know what it meant elsewhere and this was obviously a friendly and amusing deity. To that end, he showed the falcon looking in surprised pleasure as a black raven came unto the scene. In the last panel, the falcon-sun had dipped below the horizon, but a small man with a falcon head remained behind, even as the sky had darkened with a thin coating of the black earth he'd brought. His arms were outstretched in greeting as the raven approached.
What he hoped was understood was that it was an invitation. He would wait above as long as he could while the rest of him entered the first Gates of the Underworld if the unknown deity cared to visit with him. At the very bottom he drew three suns, accentuating the notion with three vertical lines. Three days from now he would wait and see if this god appeared to meet him.
With a nod of satisfaction, Re went home to get some dinner before the night came upon him again.
