Arachnodactyly, a term used since 1902 to describe abnormally long (spider-like) fingers, is a pathologic feature of several heritable conditions, notably the Marfan syndrome and congenital contractural arachnodactyly. A number of prominent artists, dating from the 16th to the 20th centuries, have depicted subjects with unusually long fingers, sometime associated with elongation of the body, neck and head. El Greco incorporated this style in many paintings. Little evidence supports any subject in any of these paintings as having a congenital deformity.

艺术中的蛛形纲动物

Arachnodactyly 是一个自 1902 年以来用来描述异常长（蜘蛛状）手指的术语，是几种遗传性疾病的病理特征，特别是马凡综合征和先天性挛缩性蛛形纲动物。从 16 世纪到 20 世纪，许多杰出的艺术家描绘了具有异常长手指的对象，有时与身体、颈部和头部的伸长有关。格列柯在许多画作中融入了这种风格。几乎没有证据支持这些绘画中的任何主题具有先天性畸形。
