Archaeology or archeology[a] is the study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography

Лев (Panthera leo) — крупный представитель семейства кошачьих рода Panthera, обитающий в странах Африки к югу от Сахары и Индии. У него мускулистое тело с широкой грудью, короткая округлая голова, круглые уши и тёмный пучок волос на кончике хвоста. У него ярко выражен половой диморфизм: взрослые самцы крупнее самок и имеют густую гриву. Это социальный вид, образующий группы, называемые прайдами. Львиный прайд состоит из нескольких взрослых самцов, родственных самок и детёнышей. Группы львиц обычно охотятся вместе, охотясь в основном на средних и крупных копытных. Лев — высший и ключевой хищник.

A monument is a type of structure that was explicitly created to commemorate a person or event, or which has become relevant to a social group as a part of their remembrance of historic times or cultural heritage, due to its artistic, historical, political, technical or architectural importance. Examples of monuments include statues, (war) memorials, historical buildings, archaeological sites, and cultural assets. If there is a public interest in its preservation, a monument can for example be listed as a UNESCO World Heritage Site. The Palgrave Encyclopedia of Cultural Heritage and Conflict gives the next definition of monument:

A mosaic is a pattern or image made of small regular or irregular pieces of colored stone, glass or ceramic, held in place by plaster/mortar, and covering a surface. Mosaics are often used as floor and wall decoration, and were particularly popular in the Ancient Roman world.

Ruins (from Latin ruina 'a collapse') are the remains of a civilization's architecture. The term refers to formerly intact structures that have fallen into a state of partial or total disrepair over time due to a variety of factors, such as lack of maintenance, deliberate destruction by humans, or uncontrollable destruction by natural phenomena. The most common root causes that yield ruins in their wake are natural disasters, armed conflict, and population decline, with many structures becoming progressively derelict over time due to long-term weathering and scavenging.
