thumb|Head of Plato, Roman copy. The original was exhibited at the Academy after the death of the philosopher (348/347 BC).
I cannot write an accurate overview of Platonism based solely on this context, as it contains only a caption about a sculpture of Plato's head and provides no information about Platonism itself, its ideas, or its significance. To fulfill your request accurately, I would need source material that actually describes Platonism.

Platonism is the philosophy of Plato and philosophical systems closely derived from it, considered the opposite of nominalism, or anti-realism. Platonism has had a profound influence on Western thought. Platonism or Platonic realism affirms the real existence of forms or abstract objects, originally to solve the problem of universals. Abstract objects are asserted to exist in a third realm distinct from both the sensible external world and from the internal world of consciousness. This can apply to properties, types, propositions, meanings, numbers, sets, truth values, and so on (see abstract object theory).
