Early thermal weapons, which used heat or burning action to destroy or damage enemy personnel, fortifications or territories, were employed in warfare during the ancient and post-classical periods (approximately the 8th century BC until the mid-16th century AD).

Incendiary devices were frequently used as projectiles during warfare, particularly during sieges and naval battles: some substances were boiled or heated to inflict damage by scalding or burning; other substances relied on their chemical properties to inflict burns or damage. These weapons or devices could be used by individuals, thrown by siege engines, or utilised as army strategy. Incendiary mixtures, such as the petroleum-based Greek fire, could be launched by throwing machines or administered through a siphon. Sulfur- and oil-soaked materials were sometimes ignited and thrown at the enemy, or attached to spears, arrows and bolts and fired by hand or machine.

A caravan (from Persian کاروان kârvân) is a group of people traveling together, often on a trade expedition. Caravans were used mainly in desert areas and throughout the Silk Road, where traveling in groups helped in defense against bandits as well as in improving economies of scale in trade.

The Exodus (Hebrew: יציאת מצרים, romanized: Yəṣīʾat Mīṣrayīm, lit. 'Departure from Egypt') is the founding myth of the Israelites whose narrative is spread over four of the five books of the Pentateuch (specifically, Exodus, Leviticus, Numbers, and Deuteronomy). The narrative of the Exodus describes a history of Egyptian bondage of the Israelites followed by their exodus from Egypt through a passage in the Red Sea, in pursuit of the Promised Land under the leadership of Moses.

The story of the Exodus is central in Judaism. It is recounted daily in Jewish prayers and celebrated in festivals such as Passover. Early Christians saw the Exodus as a typological prefiguration of resurrection and salvation by Jesus. The Exodus is also recounted in the Quran as part of the extensive referencing of the life of Moses, a major prophet in Islam. The narrative has also resonated with various groups in more recent centuries, such as among African Americans striving for freedom and civil rights, and in liberation theology.

The Holy Land, Syria, Idumea, Arabia, Egypt, and Nubia is a travelogue and the magnum opus of Scottish painter David Roberts. It contains 250 lithographs by Louis Haghe of Roberts's watercolor sketches. It was first published by subscription between 1842 and 1849, in two separate publications: The Holy Land, Syria, Idumea and Arabia and Egypt and Nubia. William Brockedon and George Croly wrote much of the text, Croly writing the historical, and Brockedon the descriptive portions.

Described as "one of the art-publishing sensations of the mid-Victorian period", it exceeded all other earlier lithographic projects in scale, and was one of the most expensive publications of the nineteenth century. Haghe has been described by the Metropolitan Museum of Art as "the best and most prolific lithographer of the time".

The Departure of the Israelites is an oil on canvas historical landscape painting by the British artist David Roberts, from 1829. It is held at the Birmingham Museum and Art Gallery.
