Tubi astronomici, Gerberto e la via Lactea
Abstract
The tubes have been associated to astronomical observations well before the invenction of the telescope. Some manuscripts of X-beginning XIII centuries represent the polar pointing used to read the hour of the night. Later images of XIII centuries have only allegoric meaning. One of them shows the King Nectanebo aiming at the Milky Way, in ancient times identificated as the Daemon Meridianus. This patristic tradition is compared to the dark legends concerning Gerbert, who described with enough details his instrument to observe solstices, equinoxes with tubes, aligned with the North pole's star.
