Albrecht Altdorfer (c. 1480–1538) was a prominent German painter, printmaker, and architect of the Renaissance period, known for his pioneering contributions to landscape painting. Born in Regensburg, Germany, Altdorfer became a key member of the Danube School, a group of artists celebrated for their expressive and innovative approach to landscape art. Altdorfer's work is characterized by its vivid landscapes, intricate details, and dramatic use of light and shadow. One of his most famous works, "The Battle of Alexander at Issus" (1529), exemplifies his skill in combining historical narrative with vast, detailed landscapes, setting a new standard for panoramic painting. This work is notable for its meticulous depiction of an epic battle scene, set against a backdrop of expansive, rolling terrain and a tumultuous sky. In addition to his painting, Altdorfer was a master of printmaking, producing numerous woodcuts and engravings that showcased his talent for fine detail and complex compositions. His architectural contributions include designing several buildings in Regensburg, where he also served as a city councilor. Altdorfer's innovative approach to landscape and his ability to blend natural scenery with historical and religious themes had a lasting impact on European art. His work represents a significant development in the transition from Gothic to Renaissance styles in Northern Europe.
