How does 馬 resemble a horse? Please see my 3 questions inscribed in the screenshot from Wiktionary:
the character 馬 existed in oracle bone script, there're numerous versions of it. then, the info quoted has some errors.

let's start:



first, rotate left 90°



now, you've a side view of a horse: head at the left, tail pointing right, 3 strokes upward represent the mane, the circles are horseshoe, the line (leg) connected it to the body.

it emphasised the big eye of a horse, the mane on its' back, and the "hairy" of a horsetail.

considering it's created several thousand years ago, with the "writing tech" of bones &amp; stone knife, forgive the abstractness :)

have fun :)
