In designing a book based on a letter of the alphabet, I discovered that the letter X is used more frequently in our everyday lives as a symbol, rather than as an actual letter. In creating the book Exposed, I began with a brief overview of the letter X. As the book progressed, the question as to the necessity of the letter X was explored, but an exact answer was not revealed. The book exposes the letter X in our everyday lives. Denoting an unknown quantity in physical science and mathematics, representing the Roman numeral for ten, the multiplication sign in arithmetic, the marking of a treasure… to name a few. X does mark the spot!
