Complete Rubaiyat of Omar Khayyam. I know some verses relatively well in Russian, but haven’t found them in the English translation yet. One of my favourite is this (my literal translation from Russian):
To live life wisely, there’s a lot to know,
Two ground rules remember for a start:
Better be hungry than eat whatever food,
And better be alone than with whoever.
Чтоб мудро жизнь прожить, знать надобно немало,
Два важных правила запомни для начала:
Ты лучше голодай, чем что попало есть,
И лучше будь один, чем вместе с кем попало.
Please note that, as I said above, this is a literal translation. I couldn’t find the English version, so I rendered the text from Russian into English, to give an idea. As I don’t know the language of Khayyam, I wouldn’t actually translate this verse from Russian, since the Russian text is already a translation. I’m writing this, having discovered that my rendition has been quoted elsewhere on the web as a variant of the English translation. It must not be used as such.
