Borghesi Astronomical Clock
name: label: maker
content: Borghesi, Francesco
notes: label: Description (Brief)
content: Conceived by Father Francesco Borghesi and constructed in collaboration with him by Antonio Bertolla at Mocenigo in South Tyrol, now in Northern Italy. The movement has no hands; the four concentric silvered brass ring dials turn independently, being read from a cursor on the glass in the hood which covers them. In addition there are subsidiary dials at right and left below and at top center of these concentric dials in addition to ten openings in the lunette through which readings may be read from small dials located behind the dial proper. This main dial plate is gilt brass richly and skillfully engraved with both figures and inscriptions including the dates 1763 and 1764 in chronograms.
