The Teachings of Ptahhotep: The Oldest Book in the World (Unabridged‪)‬

The Teachings of Ptahhotep (also known as the Instruction of Ptahhotep or Maxims of Ptahhotep) is a collection of ancient Egyptian wisdom and advice written by the elderly Vizier Ptahhotep around 2350 BCE. 

Nominally intended as an aid to his son and heir, Ptahhotep's writings offer a fascinating glimpse into the concerns of the period, from manners, customs, and lofty concerns like virtue, to the everyday and mundane concerns of navigating relationships.
