The oldest recipe of the Martinez of which I am aware is from Jerry Thomas:
1 wine-glass of Vermouth (2 oz)
1 pony of Old Tom gin (1 oz)
2 dashes of Maraschino (1/4 oz?)
1 dash of Boker's bitters
Garnish with a quarter-slice of lemon in the glass (not sure if this means fruit or just peel)
I would imagine that the vermouth back in those days was perhaps somewhat closer to Carpano Antica Formula -- which is to say, richer, less sweet and more herbal/bitter than Cinzano or M&R. JT says, "If the guest prefers it very sweet, add two dashes of gum syrup," which makes me believe that he thought it was already a sweet drink.
Other recipes that come fairly soon after JT specify equal parts gin and vermouth, other kinds of bitters (or just generic "bitters") and leave out the maraschino in favor of either curaçao (which, per previous discussions here, was often so sweet and lacking in orange flavor that it was used as a generic sweetener) or just simple syrup. Even as recently as the Savoy Cocktail Book, the recipe for the Martinez is comprised of equal parts gin (no longer Old Tom) and vermouth with orange bitters and either curaçao or maraschino (curaçao being listed first). I'm not sure how we came to believe that maraschino is what makes a Martinez a Martinez, except that maraschino is in the earliest recipe we have.
Interestingly, the Old Waldorf=Astoria Bar Book does not have a Martinez recipe. It does, however, have a Martini recipe consisting of equal parts Old Tom gin and Italian vermouth with orange bitters, a lemon twist and an olive garnish. With the exception of the olive, it's not dissimilar from recipes for the Martinez published 40 years earlier.
As John points out, just as with many old cocktails such as the Manhattan, the ratio of gin to vermouth has been reversed in modern incarnations of the drink and now it is common to see a 2:1 ratio of gin to sweet vermouth (although, just as with the Martini and Manhattan, it is often rewarding to mix the drink in equal parts or even return to the vermouth-based original). One interesting modern Martinez-inspired drink that I like very much was developed by Chad Solomon. It consists of 2 ounces of gin, 1 ounce of bianco vermouth (a sweet white vermouth), 1/4 ounce of maraschino and a few dashes of bitters (John's Abbot's bitters being my preferred for this drink).
