A reproduction of a chart from Tamrapichaisongkram, which is canon of texts concerned with the defensive arts which had been in use since the Ayutthaya Era. This chart depicts the elements used in determining an auspicious and victorious name, describing how battlefield categorization corresponds to eight creatures (mouse, tiger, garuda, elephant, etc), and so a victorious name is based upon the day of week on which someone is born, then corresponds to a creature on the chart, as well as a set of letters which are associated with desirable attributes.
