I'm thinking of pursuing Latin. Recently I've been very interested in humanistic studies and thought that learning (Classical) Latin would be a great way to read primary sources from Classical times, the Middle Ages, and certain parts of the Renaissance. This would be my first "dead" language, so what would be the cons of learning it (besides the fact that "nobody speaks it anymore")? Besides the aforementioned one, what would be some pros to learning Latin? I already speak Portuguese, French, Spanish, and Catalan, so I doubt it would be of much help if I wanted to learn, say, Italian or Romanian.
What about a text to guide me through my studies? I've been eyeing Wheelock's Latin and the accompanying workbook, which are very highly reviewed.
Just one last question: should I pay much attention to the mācrons in spelling?
