I am having trouble finding information on the Greek presence in Spain around the year 600 - 500 BC. I have to write articles in spanish about important events, culture, and the greek influence on Spain during that time period. I would appreciate anyone that posts links to sites that talk about greek culture and influence on Spain during that era or share your knowledge with me.

Thanks

How hard is it to learn greek? Comparisons would be nice (harder than spanish, easier than japanese, etc.). also, my second question is what's the best online resource for learning it that you've seen?
i have a very good english vocabulary (despite being 14 years old) and i'm a native english speaker. in fact, one reason greek interests me is because i respect the greek influence on english.
