What's in Caesar's Box? Mystery Cache

Welcome, Julius Caesar!

Note: The cache is not located at the published coordinates - they are BOGUS.  They're just the location of a nice park not (too) far from GZ.

GZ is absolutely muggle central at ALL times during the day and you might find yourself face-to-face with any number of them from any direction at any time.

Want a puzzle? You got one! Depending on how often you read popular novels you'll either recognise the puzzles below as mangled versions of what they really are or just sit there going … huh?  Don't be put off by the number of steps involved!

It's 100% possible to solve all this without using *any* of the hints attached to this cache listing - if you do, please say so in your log and I reckon you'll earn everyone's respect  That said, there are 2 hints for this cache as I'm not intending this puzzle to be unsolvable.  They should light the way reasonably clearly if you engage the ol' grey matter …

Part 1

Find me on The Googles on The Internets

1. A = How many members were there in the political alliance the 'First Triumvirate', of which Julius Caesar was a member?
2. Julius Caesar was considered a great man.  BC = the racing number of the man voted Australia's greatest ever touring car driver.
3. D = The number of letters in the name of the country often considered the origin of the salad named after Julius Caesar.
4. EF = The date in July that Julius Caesar was born.
5. GH = Julius Caesar's age, when he died.
6. I = The last name of the man mentioned in all the questions, so far.  Just the name … to make sure you're paying attention.  ;-)

Part 1a

Now that you've learnt a few things, it's time to get stuck in ...

Part 2

Part 3

You're on your own from here … get that brain going!

Part 4

Part 5

If you've done everything correctly so far, part 4 should make more sense now ... write it down when you figure out the pattern.

Part 6

(Cell A4)(C)(Cell G3)(Cell C4)

Part 7

Use the following simple substitution formula in conjunction with your answers in the previous parts to work out the final cache coordinates.

S 37° 4(A+3).(E)(H+2)(F) E 144° (G)(C+2).(D)(B + 10 - 2)(E + F + 2)

Feel free to use geocheck.org to check your solution by clicking the image below ...

Having trouble?  There is a definite pattern in the puzzles above ... you just need to figure it out.  It's difficulty rating 4 though so that's all I'm saying.  :-)

Please replace the cache exactly as you find it - thanks!
