What is the significance of the number 12 in Freemasonry?

Twelve Fellow Crafts figure prominently in traditional history following the plot against Hiram Abif. Though fifteen had originally joined in the conspiracy, twelve recanted prior to its execution and voluntarily confessed to King Solomon, who subsequently tasked those twelve brethren with the search for the Master, as an article on the Grand Lodge of India's website records.

Early English manuscript traditions also attach symbolic significance to the number twelve in the form of lodge lights. The Graham Manuscript of 1726 lists a traditional set of twelve "Lights"—comprising divine, celestial, officer, and working tool symbols—as a paper read before Quatuor Coronati Lodge notes.

Beyond these traditional accounts and early manuscript references, the supplied printed literature contains no further discussion of the number twelve within Craft Masonry.
