* These authors are thought of traditionally as the actual authors. There is some speculation however due to the fact that, at the end of these works, it mentions the death of the authors in question. Also the dates mentioned are in conjunction with the exodus, which took place from Egypt. The exact time of this exodus however is also in question, but most commonly assumed to have taken place around one of the above mentioned dates.  

! Moses - Psalm 90

- Heman the Ezrahite - Psalm 88

- Ethan the Ezrahite - Psalm 89

- Solomon - Psalm 72, 127

- David (73 times) - Psalms 3-9, 11-32, 34-41, 51-65, 68-70, 86, 103, 108-110, 122, 124, 131, 133, 138-145

- Asaph (12 times) - Psalms 50, 73-83

- Sons of Korah (9 times) Psalm 42, 44-45, 47-49, 84-85, 87

- Author unknown - (49 times) the remainder

- The Septuagint (an early Greek translation of the Hebrew Bible from around 200 BC) gives some additional authorship identification, as follows:

- Jeremiah - Psalm 137

- Haggai and Zechariah - Psalms 146-147

- Ezra - Psalm 119

- Hezekiah (15 times) Psalms 120-134

- The psalms, based on the authorship attributions, would then date between the 15th century (or 13th, depending on the time of the Exodus) and the 5th century, by which time the book probably took the form it currently has.
