“They shall construct an ark of acacia wood two and a half cubits long, and one and a half cubits wide, and one and a half cubits high”.
Obviously fans of design to whole number harmonic rations, the authors of the Book of Exodus provided the primary geometric forms of the Ark of the Covenant. The height and depth of the ark is set at 1 1/2 by 1 1/2 cubits, which works out to a square. This form was seen in ancient times as a manifestation of the one-to-one relationship inherent in the harmony of the heavens (i.e. the foundational musical scale) as “unity”. Since the length of the arc is defined as 2 1/2 cubits, the height-to-length ratio of the resultant rectangle is 1 1/2 to 2 1/2 or, rounding up, 3:5. This ratio happens to produce a perfect sixth harmonic.
Which, after perhaps six days of creative endeavour with a chisel on stone, is also represented by this form:
You gotta wonder…..
