The English word "obituary" seems to come from the Latin verb obire. One can derive the adjective obituarius from that verb, and using the neuter obituarium would make possible translation. However, I have not found this or any other word used in Latin to mean an obituary. I can think of other ways to render "obituary" in Latin, including scriptura memorialis (a direct translation from Finnish), but I don't know what would be idiomatic. There is also the phrase in memoriam, but it requires an accompanying noun to make sense.
What would be a good Latin phrase for "obituary" and why? Is it attested, or are there other good reasons to use it?
