I'm trying to make alerting messages on my website feel old-fashioned. Is there any straightforward approach to translate modern English into ancient English? I can't tell which exact stage of English is what I want, because the history of English language is an overwhelming reading work for me.
I'll try to explain my question by giving examples. The following sentence is not what I want, because I don't think an average English native speaker can understand it with no effort.
- Her swutelað seo gecwydrædnes ðe
I expect those which seem old, but is still comprehensible by common English speakers:
- Thou shalt regret thine action!
- I thank thee for thy contribution.
- In return to thy service, I grant thee the gift of Immortality!

I think a word-by-word lookup table should be enough to do this, isn't it?
