Step 1 : Introduction to the question "Which Old Testament book commemorates the destruction of Jerusalem?"
...The Book of Lamentations is a collection of five separate poems lamenting the destruction of Jerusalem. The poems commemorate the city's fall, comparing it to a bereaved widow grieving her loss. The poems take a fairly bleak tone, acknowledging God's just anger and punishment, and offering little hope for future restoration. Though Jeremiah was traditionally believed to be the book's author, the tone and writing style don't match his other writings, so this perspective is no longer generally accepted.
