Two nights ago the moon was full and rose early and low over Anasco Bay. It was cloudy, dense dark clouds and the moon initially was a dark amber color and as it rose became more yellow and then silver white. I'm not sure what it is about the moon, the water, the night but it does provoke reflection.
There are quite a few poems about the moon on water... many deal with topics of love, love lost, loneliness, solitude and quiet. I found this one in a wonderful collection about Puerto Rico from 1941 entitled Puerto Rico in Pictures and Poetry.
Tropical moon, how you glow tonight,
High o'er the mountains, luminous, bright.
Telling earth's children, from near and afar,
God watches o'er them like yon evening star.
