Final answer:
An arcade is a row of arches that can be found in various architectural structures. Long arcades are characterized by a row of arches stretching across a long distance, while short complex arcades are more intricate and consist of multiple layers or levels of arches.
Step-by-step explanation:
An arcade is a row of arches, often seen in architectural structures such as churches and mosques. It is a series of arches that provide support and add visual interest to a building. There can be different types of arcades, including long arcades and short complex arcades.
Long arcades are often found in basilicas and other large buildings. They are characterized by a row of arches that stretch across a long distance. These arcades create a sense of unity and rhythm in the overall design of the building.
On the other hand, short complex arcades are more intricate and consist of multiple layers or levels of arches. These arcades can be seen in structures like the Great Mosque at Córdoba, Spain. They add complexity and visual richness to the building, with different shapes and sizes of arches creating a dynamic interplay of light and shadow.
