39. Kemp 1989, 236–9; M. Cianchi 1984, 45–55. 这些设计图案和同样绘于1487年前后的CA 824v/302v–a上的扑翼飞机很像。B 74v上的设计是詹姆士·温克构建全尺寸模型时的主要参考来源（Tetra Associates for the Hayward Gallery, London, 1989）。模型的翼展超过35英尺，全长大概 10英尺。材料是列奥纳多特别准备的，或是当时只能取得这些，包括山毛榉木材、铁和黄铜、麻绳、油麻绳、皮革和动物油脂，重达650磅。这也暴露出列奥纳多的飞行器的最基本问题：缺乏一种足够轻的材料来达到飞行所需的功率重量比。

48. It might be an edition of Albertus Magnus’s work on minerals, e.g. Mineralium libriv (Rome, 1476). The ‘lapidario ’ of the Madrid list is thought to be Speculum Lapidum (The Mirror of Stones) by Camillo Leonardi di Pesaro, published in 1502 with a dedication to Cesare Borgia; Leonardo may have known the author. This book is too late for the Trivulzian reference.
