Another "One Tip:"
If you are not sure about how to connect with Mythic Europe, where to start creating a legendary character who truly belongs, take the Strong Faerie Blood virtue, choose a fairy (spelling deliberate) variety that appeals to you, and go from there.
Whereas Hermetic Magic (tm) is totally made up and not very medieval, fairies have that authentic medieval feel, even when they are from the Renaissance or later. You can choose a 'species' of faerie if you like, a Dwarf, Sidhe, Alfar, Leshy, Nymph, Brownie whatever, but you can also go with "faerie wizard" or "faerie knight" or "church faerie" or Rumpelstiltzkin or even (maybe) "one of Santa's helpers." Just about anything vaguely mythological works, and gets you started right. "It might not be true, but my family has a legend that we are descended from Merlin, who was half-faerie." "My father was a priest unable to resist a Nymph...." "I am a byblow of the Genie of the Lamp." "My mother was a princess from the Court of Winter, who ran off with a troubadour. (That's what she said, anyway.)" Lots of choices. You might have to work with your GM to choose an appropriate special bonus, though a +1 to an attribute or a positive Faerie Correspondence should always be reasonable.
This is also a great virtue for characters starting right after Gauntlet. Second Sight is nice, albeit a lesser minor virtue. The ability to see in the dark is nice, though definitely not worth a minor virtue for a magus (unless you are in a saga that is very, very strict about scrying...) You also get a special bonus that is usually just shy of a minor virtue (though Dwarves do better!) And you get a distinctive appearance. Why, then, the love? You start aging at 50 and have a +3 bonus for aging rolls. Again, a magus is not likely to care about a small aging bonus... but that's the wrong way to use the virtue. Instead, if you start your character 15 years older than he would have been, you get 225 points of pre-apprenticeship xp. You cannot use these xps freely, but you can use them to round out your character: Charm, Concentration (very useful for magi), Etiquette, Charm, Brawl, Second Sight, etc, and maybe a Faerie Correspondence. Then you can pour all of your apprenticeship points into Arts, Magic Theory and other necessary abilities for a magus, and still have a very well-rounded character. And if you choose a useful Faerie Correspondence (for which Strong Faerie Blood provides a nice +3 bonus), you can tap into some Real Power.
225xps, see in the dark, second sight, a minor virtue and a deep connection to Mythic Europe. All for 3 points.
One of my favorite virtues.

Oh, I see - you could make duration concentration spells last longer and open arcane tunnels at any ranges shorter than arcane connection. Then you could get by with all of your sponts at range touch and duration concentration, very often these would then be at much lower level than without the rego vim tools more within your abilities and hey the Rego Vim spells in your device don't have to be art specific.
