1 - since it's a library, i'd like putting a sculpture from ancient greece, probably from the hellenistic epoch.

2 - i'd also like the statue to be from a famous person from that time, a philosopher of possible.

3 - i'd want the statue to be of a man sitting down on a tree stump with a book on his hands (either writing or reading), to demonstrate the love for reading.

4 - i'd also like to have the statue with a darkish colour and high contrast, as well as a statue that resembles balance and a little movement on his head if he is reading or on his hand if he's writing.

hope it ,
