The Practice and Method: How to Draw a Horse from the Side Using the Compass and Straightedge According to Geometry or Earth Measurement

Previously, we presented various new illustrations of horse drawing. Now we will continue and show how to draw a horse from the side using the compass and straightedge according to geometrical art, but in a particular way: First, using the compass and straightedge within its own proportion. Before beginning with the circle, create a rectangle and divide it into 9 equal sections as shown by example A. E. S. T. C. B. N. I. H. L. W. M. P. D. A. M. Then divide one of these sections in half and further divide it, and then subdivide further into two equal parts.

After these divisions, mark a point in the middle. Plan where the midpoint will be - illustrate a circle from the line DC H. Z. from point E up to point W. Next, the center of the horse's head will rise, and essentially align it with this line. Create a perpendicular line at one and a half feet long. You will reach the point A, for the beginning of the horse. Align these points and make the necessary connections. Let the circle guide you on how much space the drawing will take.

The guide includes fine measurements: for example, the length and breadth of certain points are set out carefully. For any adjustments through errors in the alignment, there are suggestions for correction using the compass - which decide particular lengths and angles. Establish the dimensions first using both geometry and precision described in the Alciato's principles. When the rectangular sections are finalized and adjusted for the horse shape, follow the described process closely as reiterated throughout these guided illustrations.
