The term marts is an archaic word that denotes marketplaces where goods are bought and sold. In the context of J.G. Holland's poem "False and True," the word is used to evoke the idea of material wealth and the superficial allure of appearances. The phrase "As in the marts was never bought or sold" suggests that the golden armor, representing falsehood, is more dazzling than anything found in the marketplace, highlighting the contrast between superficial beauty and deeper truths.

The word marts derives from the Middle English "mart," which itself comes from the Latin "martis," meaning "of Mars," the Roman god of commerce. Historically, marts were significant centers for trade, and their usage in poetry often reflects themes of value, deception, and the contrast between appearance and reality. Related terms include "market" and "bazaar," which also denote places of trade but may carry different cultural connotations. When using the term in modern contexts, it is important to recognize its archaic nature and to consider whether a more contemporary synonym might be more appropriate for clarity.
