The Cryptic Room - Hiram Abif bows before two angels

According to Masonic tradition, Hiram Abiff was the chief architect and engineer in constructing the Temple of Jehovah (Solomon's Temple). Hiram Abiff was also a teacher of Geometry.

And Hiram king of Tyre sent a letter to Solomon, saying: Because the Lord hath loved his people, therefore he hath made thee king over them. And he added, saying: Blessed be the Lord the God of Israel, who made heaven and earth, who hath given to king David a wise and knowing son, endued with understanding and prudence, to build a house to the Lord, and a palace for himself. I therefore have sent thee my father Hiram, a wise and most skillful man, The son of a woman of the daughters of Dan, whose father was a Tyrian, who knoweth how to work in gold, and in silver, in brass, and in iron, and in marble, and in timber, in purple also, and violet, and silk and scarlet: and who knoweth to grave all sort of graving, and to devise ingeniously all that there may be need of in the work with thy artificers, and with the artificers of my lord David thy father.
