ASAM, Cosmas Damian
(1686-1739) Baroque German painter Asam Cosmas and his brother Egid, sons of the Bavarian painter Hans Georg (1649—1711), were church decorators and designers in whose work S. German Baroque achieved its zenith. Cosmas Damian (1686—1739) was a painter and architect of the monastic church of Weltenburg (1717—21). In his painting illusionism is carried to its furthest extremes, e.g. his frescoes in the church of Maria Viktoria, Ingolstadt (1736), and the Alteglofsheim Palace in Brevnov (1730). His use of light colours tends to the style of Rococo. Like his brother he held high positions in S. German courts. Egid Qturin (1692—1750) was stucco-worker, sculptor and architect; his churches include the collegiate church at Rohr (1718—25) and St Johann Nepomuk (called the Asam) church, Munich (1733-c 1750), although Cosmas may have helped in the latter. All his sculpture of any importance is designed for churches and his best works are his altarpieces, e.g. the Assumption of the Virgin at Rohr and the St George at Weltenburg. The brothers worked in such harmony that it is usually difficult to distinguish their work. They were employed to redecorate Romanesque or Gothic churches (as at Freising cathedral, 1723/4, or St Emmeram's church, Regensburg) but their masterpiece is the S. Johann Nepomuk church, Munich, where painting, sculpture, stucco and architecture serve the illusive confusion of the real and imaginary worlds (*Baroque).
