One of the first Dips was the Greek Tzatiziki.

 

The history of Salsa sauce originated with the Inca people. Salsa (combination of chilies, tomatoes and other spices) can be traced to the Aztecs, Mayans and Incas. ... Aztec lords combined tomatoes with chili peppers, ground squash seeds and consumed them mainly as a condiment served on turkey, venison, lobster, and fish.

Spreads are different from dips, such as salsa, which are generally not applied to spread onto food, but have food dipped into them, instead.
