Why are Arabic numerals thick and thin in different places from the alphabet?

Question

Thick and thin in the alphabet is like holding an old reed pen so that vertical and descending diagonal are thick, while horizontal and ascending diagonal are thin. But in the Arabic numerals 2, 3 (flat-topped), 5 and 7, the horizontals are thick. Why is this?

Answer 1

There is a reason behind this because in olden days they didn't have pens or pencils that we use today. All they used to write with was some hand-made pens made out of dried slim shoots of bamboos by cutting the edges of tip with sharp knife. They would cut the tip of the shoot in the shape of a nip i.e.not pointed but flattend on the tip with thin width just like the bigger version of ink pen's nip.But of course their pens used to be big and long and highly decorated with feathers etc.just to give a royal look. Perhaps the first Arabic writer also used the same kind of pen to write Arabic that's how it gave those thick and thin letters. It's just a common sense. You could try one it 'll surely be more or less the same fonts style.

Answer 2

No, you must be confused. in Calligraphy the pen is held the same for the numerals as for the letters for Italic writing. If you are doing Uncial then the Uncial style of Arabic numerals should be used so that it matches
