Atilius recognized it as a map of the nation they were in. But was very confused what the sun meant. Was it where they were currently or where their capital was? Atilius asked pictographs what the Sun meant. With the capital representing a Sun = a drawing of a Crown; and the port they are in with the Sun = Ship(Port). And if the Sun meant the capital, may they see the leaders of this nation.
Then, Atilius grabbed another piece of paper, this time asking his personal Royal Naval Artist if he can draw positions of respect that have been documented by Solarian travelers before. The paper showed a Crown on the top with an equal sign below it, and then pictures of different forms of respect to royalty.
