I’ve been studying ancient Greek since Fall 2006. Although my original goal was to read Homer’s Iliad and Odyssey in Homeric Greek, I started with Attic Greek, a quite different dialect. There are more textbooks for Attic; it is considered the most “elevated” dialect, and it is the language of classical Athens, writers like Plato, Xenophon, Aristotle, Lysias, Sophocles, etc. “It seemed like a good idea at the time.”
After three years of very slow progress in Attic, I decided that I had made as much progress in Attic as would be useful in my reading of Homer. I hadn’t mastered Attic as well as I envisioned, and moved on to Homer (my original goal).
From 2010 through 2012, I focused on Homeric Greek, reading and re-reading The Iliad and Odyssey. Again, I did not achieve anything like “fluency.”
Since early 2012, I have gone back to Attic.
