This article uses Galen’s De complexionibus and its reception as a thread to examine the part played by the sense of touch in the assessment of bodily mixtures. According to Galen, complexions were assessed by touching patients with the skin of the palm of the hand because it is “at the precise midpoint between all the extremes” and, thus, well-mixed. This article examines how this extraordinary claim about the discriminative power of touch was received from the late Middle Ages up to the early modern period, with a special focus on Renaissance thought. By following Galen’s text and its various forms and appropriations, the aim is to illuminate the fluid understanding of the Galenic notion of ‘complexion’ (complexio) in relation to changing epistemologies of touch in Renaissance medicine, notably by shedding light on the anatomical concept of ‘substance’ (substantia).

混合物可以通过触摸来识别吗？意大利文艺复兴时期医学界对盖伦《论肤色》的接受

本文使用盖伦的肤色并将其作为一条线索来检验触觉在评估身体混合物中所扮演的角色。根据盖伦的说法，通过触摸患者手掌的皮肤来评估肤色，因为它“位于所有极端之间的精确中点”，因此混合得很好。本文探讨了从中世纪晚期到现代早期，人们如何接受这种关于触摸辨别能力的非凡主张，并特别关注文艺复兴时期的思想。通过遵循盖伦的文本及其各种形式和挪用，目的是阐明对盖伦“肤色”概念的流畅理解（情结）与文艺复兴时期医学中触摸认识论的变化有关，特别是通过阐明“物质”的解剖学概念（实质）。
