It seems that Hesiod left 3 works intact. Can anyone tell me what they were called in the language used at the time? I understand the idea of titling their work may not coincide with how we use it, but I guess what I am asking, is Hesiod's work ever mentioned outside of his own Writings?

See www.ellopos.net/elpenor/koinonia/topic.asp?TOPIC_ID=359&SearchTerms=titles" target="_blank">https://www.ellopos.net/elpenor/koinonia/topic.asp?TOPIC_ID=359&SearchTerms=titles for the attitude of the authors themselves concerning titles. This is also the case with references.

It is common for the ancients to refer to a work just by mentioning the author, in phrases such as "Plato says", "Homer says", etc, without precise reference to work (of course not to verse or chapter, etc). Here is a search on the complete works of Plato, where Plato mentions Hesiod: www.ellopos.net/search/search.php?query=hesiod&type=and&search=1&category=1" target="_blank">https://www.ellopos.net/search/search.php?query=hesiod&type=and&search=1&category=1
