Identifying a point by year round observation is not the same as being able to use it on one particular night at sea, if your life depends on it. You don't have the luxury of observing its position for a few months, to determine the point it rotates around.
And it wouldn't be particularly useful anyway, while lacking a stable frame of reference in the first place. I mean, you're going to plot that circle in relation to WHAT frame of reference?
For trips any longer than maybe crossing the 32km (about 20 land miles for you Imperials) from Antykithera to Gramvousa, since you mentioned going to Crete, being wrong even by a couple of degrees can be fatal.
At any rate, for better or from worse, we have accounts for all the period from Homer to Acts about ships going around the shore. In fact, the whole Odissey is what happens when you get blown into the open sea. The guy only had to cross from Turkey to Greece, but once he lost sight of shore, hijinks ensued. Seems to me like if the ancients had a reliable way to find which way is north at sea, the whole story would have come across as a pretty piss-poor excuse to get lost.
