What is the poem written on graves of people?

There isn't one specific poem written on all graves. Epitaphs are the inscriptions on tombstones, and they can vary widely. Some are traditional, others are personal, and many are simply the name and dates of the deceased.

Here are some examples of common epitaphs:

* Traditional: "Rest in peace," "Gone but not forgotten," "Asleep in Jesus."

* Personal: A short poem or quote that reflects the deceased's life, beliefs, or personality.

* Humorous: A playful or lighthearted inscription that captures the deceased's sense of humor.

* Simple: Just the name and dates of birth and death.

You can also find many poems that are commonly used in epitaphs, such as:

* "Do Not Go Gentle into That Good Night" by Dylan Thomas: A powerful poem about fighting against death.

* "The Road Not Taken" by Robert Frost: A poem about making choices in life.

* "Stopping by Woods on a Snowy Evening" by Robert Frost: A poem about finding peace in nature.

Ultimately, the poem or inscription on a grave is a personal choice, and it should reflect the life and memory of the deceased.
