Three mottos, Temple of Apollo, Greece

At the entrance of the Temple of Apollo at Delphi, ancient Greece, three famous Delphic maxims (箴言) were inscribed. These succinct mottos were central to Greek philosophy and ethics:

1. Γν?θι σεαυτ?ν (Gnōthi seautón) —
   Know thyself （認識你自己）
   
   
2. Μηδ?ν ?γαν (Mēdén ágan) —
   Nothing in excess（凡事勿過度）
   
   
3. ?γγ?α π?ρα δ'?τα (Engýa, pára d’ áta) —
   Give a pledge and ruin is near（立誓則禍隨之；承諾易招災）
   
   

These sayings reflect key principles of moderation, self-awareness, and caution — foundational to classical Greek thought and later Stoic philosophy. 阿波羅神殿門口三句箴言 Three mottos at the entrance of the Temple of Apollo
