Geminiano Rondelli - Euclide - Planorum ac solidorum Euclidis Elementa - 1693

Planorum, ac solidorum Euclidis Elementa. 以更便于作者之论证者之方式，希梅尼亚诺·隆德利哲学博士在博洛尼亚大学普及性数学学院的日间讲解中，对欧几里得《元素》之平面与立体几何作出解释与说明，献给博洛尼亚大学参议院之众位尊贵院士。

博洛尼亚，长久出版社，1693。

这是一本有趣的十六世纪博洛尼亚版欧几里得《元素》之注释版，由数学家吉米尼亚诺·隆德利（1652–1735）编校、评注并以木版图示，博洛尼亚大学的数学教授。
卷册专注于平面几何与立体几何，书内以极其丰富的木刻几何图表与图形来图解定义、命题与证明。

图解设施以六幅大型折叠几何图（表格 I–VI）完善，皆完整存在。

扉页印有博洛尼亚参议院之徽。卷末是一幅描绘大力神赫拉克勒斯与九头蛇的巨大木刻图案。

对照本之整理已核对：前四页前言；A–Z、Aa–Bb 等册页均完整；共 395 页有页码，末尾为未编号之页。六幅折叠几何图（表格 I–VI）全数齐全。完整的版本。

本书采用同期的全生皮硬封装订，脊背有手写题名。此版本经保守性整修，伴随装订的加固及将文本体重新锚固于原封表。原始的羊皮纸及装订之历史成分已得以保留；这并非现代再装订。

在整修过程中，曾移除贴在封面的前封面里的外借人印章，因为其颜料易转移至纸面。仍可见到此前外借人贴的轻微色迹，以及早期的手写出处记载。

羊皮纸呈现自然的时间痕迹，轻微擦痕、污渍与边缘小缺陷。内部纸张总体保存良好，偶有黄褐变、污点及随年龄而来的小痕迹。少量边缘瑕疵。文本、图表与图形仍清晰可读。

六幅折叠的几何图均完整且保存良好，折痕正常，使用痕迹极少。

这是一本博洛尼亚十六世纪有趣版本欧几里得《元素》的真正且完整之版，特别值得称道之处在于同期羊皮封面、文本中大量木刻几何图表，以及全部六张折叠图的存在。

EUCLID – Geminiano Rondelli

Planorum, ac solidorum Euclidis Elementa. Facilioribus Auctorum demonstrationibus a Hiemyniano Rondelli Philosophiae Doct. in Universali Studio Bononiae Scientiarum Mathemat. de mane Professore explicata, ac Illustrissimis atque Amplissimis Senatus Bononien. Patribus consecrata.

Bononiae [Bologna], apud Longum, 1693.

An interesting seventeenth-century Bologna edition of Euclid’s Elements, edited, commented upon and illustrated by the mathematician Geminiano Rondelli (1652–1735), professor of mathematics at the University of Bologna.

A work devoted to plane and solid geometry, richly illustrated throughout with numerous woodcut geometrical diagrams and figures, accompanying the definitions, propositions and demonstrations.

The illustrative apparatus is completed by six large folding geometrical plates (Tab. I–VI), all present.

Title page with the arms of the Senate of Bologna. At the end of the volume is a large woodcut device depicting Hercules and the Hydra.

Collation of this copy has been checked: 4 preliminary leaves; gatherings A–Z, Aa–Bb, all complete; 395 numbered pages, followed by final unnumbered pages. All six folding geometrical plates (Tab. I–VI) are present. Complete copy.

Contemporary full stiff vellum binding, with manuscript title on the spine. The copy has undergone a conservative restoration, including consolidation of the binding and reattachment of the text block to the original covers. The original vellum and historic components of the binding have been preserved; this is not a modern rebinding.

During conservation, a bookplate formerly attached to the front pastedown was removed because its pigment was transferring onto the paper. Light reddish traces from the former bookplate remain visible, together with early manuscript ownership notes.

The vellum shows natural signs of age, light rubbing, staining and minor marginal defects. Internally, the paper is generally well preserved, with occasional browning, staining and small age-related marks. A few minor marginal defects. Text, diagrams and illustrations remain clear and legible.

The six folding geometrical plates are complete and well preserved, showing the usual folds and only minor signs of handling.

A genuine and complete copy of this interesting seventeenth-century Bologna edition of Euclid, particularly attractive for its contemporary vellum binding, its very rich series of woodcut geometrical diagrams throughout the text, and the presence of all six folding plates.
