What were two classical values that inspired the renaissance humanists?

Two classical values that inspired renaissance humanists were Neo-Platonism and Hermeticism. The resurgence of Platos teachings was prevalent in Italy and was instrumental in Medici's attempts to heal the growing schism between the Catholic and Greek Orothodox churches. Hermeticism posited the existence of a single unified theological truth. More generally, both platonism and hermetisciem described that there are essential truths which were a philosophical ancestor to the concept of natural laws which became the foundation first of Humanism, then of the Enlightenment.

I believe those two classical values are rationalism and humanism

Rationalism refers to the value of utilizing emphirical method in order to analyze certain circumtances around us.

Humanism ont he other hand is the value that put the benefit of collective group on top of individualistic needs.
