hark(en) back to (something)

1. To cause one to think of or recall something. (The spelling "harken" is actually a variant of the archaic word "hearken," which originally meant "to listen" but is more commonly used in place of "hark" in this idiomatic phrase.) That song harkens back to an earlier time in my life.
2. To have originated or begun as something. You know, our modern cell phones hark back to those old rotary phones you like to make fun of.
3. To revisit or recall something mentioned earlier. Before we get too upset, let's all harken back to the real reason we're here today.
