How is tempera paint made? Why are there many examples of tempera throughout history?

Answer and Explanation:

Tempera is traditionally created by hand-grinding dry powdered pigments into a binding agent or medium, such as egg yolk, milk (in the form of casein), and a variety of plant gums.

Bc tempera painting was the main canvas for painting medium for nearly every painter in Europe (I hope that makes sense)..

i believe the answer is: a.  abstract forms were often used to represent human figures.

representing human figures in abstract forms is often used in the geometric period, not hellenistic  period.   during the hellenistic  period,   aesthetic value derived from creating arts which mimic the actual shape of a certain object or individuals.
