Mycenaean architects experimented with the use of posts and lintels as elements of more complex architectural plans. To this day, the traditional two vertical supports and one horizontal beam are still used for doorways and basic structures. Historically, it was believed that the farther apart you could spread your pillars or posts, the more wealthy your city was.

The corbeled arch is most commonly seen under bridges or on bottom-level doorways. These arches are built by progressively placing stones or bricks over the edge of the one prior and working your way toward the apex or peak. However doing this meant that a counterweight was required to keep the arch from collapsing, hence why corbeled arches are only seen underneath or on the bottom side of buildings and structures.

The "Keystone" is the most important stone in the Roman Arch. It supports the entire archway, and bears the most weight to disperse. This stone is often exaggerated and decorated or set bigger that the other stones to make it stand out, as shown above. The Keystone block creates a static equilibrium in forces due to its position, exerting the forces evenly down the sides of the arch. A huge mathematical achievement in history.

The Roman Archway made the growth and development of the Gothic and Horseshoe arches possible. The concept of the keystone began the evolution into rounded and curved arches without the need of a single stone to support the whole thing. The maturing of science and peoples understanding of gravity and balance enables architects to use the original idea of the Roman Arch and take it to lengths that the 2nd Millennium Romans could never even dream of.

The use of the pointed arch, or gothic arch, in turn, led to the development of the pointed rib vault and flying buttresses, combined with elaborate tracery and stained glass windows.
At the Abbey of Saint-Denis near Paris, the choir was reconstructed between 1140 and 1144, drawing together for the first time the developing Gothic architectural features. In doing so, a new architectural style emerged that emphasized verticality and the effect created by the transmission of light through stained glass windows.

The first horseshoe arches were employed in the Umayyad Mosque of Damascus. At Qasr al-Hayr al-Gharbi, it appears a lot in the ruins of Qasr al-Qastal and on the walls of the Umayyad palace at the Amman Citadel in present-day Jordan. The horseshoe arch is considered to be the first characteristic Muslim adaptation of the arch, even though its origins are controversial.

The Roman arch I believe has the biggest jump in architectural development because it uses both vertical and horizontal pressure thanks to the "keystone". This form of arch would have taken the inventor a lot of trial-and-error and time on a sketchpad to figure out how to perfectly balance the stones on either side of the keystone. This massive jump in development lead to the building of the great Roman Colosseum, a piece of history that is still admired by people today.
