Final answer:
The riddle is related to English literature, using metaphorical language to hint at various poetic themes and concepts rather than presenting a direct mathematical or historical query.
Step-by-step explanation:
The question appears to be a riddle that integrates elements of mathematics and recreational games, specifically referencing a square with equal sides and a number significant in a deck of cards. However, this is not a mathematical or historical question but rather one related to English literature or poetry, where the riddle might be found within the text or as a means to engage with poetic devices.
The various references in the riddle-like clues are metaphorical in nature, and they do not pertain directly to the factual subjects of the other disciplines mentioned. It speaks to the grandeur of life and numbers, to the depth of the human experience, and possibly to the concept of infinity, as it mentions 'a perfect balance' and a 'lucky number' which could refer to many things in life and literature.
