The number 153 is well known as one of the important numbers from the bible's New Testament. "Simon Peter went up, and drew the net to land full of great fishes, a hundred and fifty and three: and for all there was so many, yet was not the net broken." - John, 21:11 This may be an ancient hint at the ratio found between the length and width of the vescica pisces, also known as the fish bladder, or the "Jesus fish," because it is the oval shape which makes up the body of the Christian fish symbol, the ichthys. The ratio equals the square root of 3 and is usually written 265/153, or the less common 1351/780 which is also equal to the square root of three. Notice how in the second ratio, the first number also includes the digits 1, 5 and 3. The square root of 3 is used in many examples of Gothic architecture.
