|Brief Description:||Martin explains the visibility of the transit of 1761 by giving three views of the earth, showing the hemisphere facing the sun at the beginning, middle and end of the transit. This is the only known surviving copy of his print. |
There was much discussion before the 18th-century transits of the best places from which to make observations. Several authors compiled maps to help in the decision-making process.
This sheet has a more didactic and popular purpose. It is intended to explain the visibility of a transit, and shows three views of the Earth at different moments during the transit of 1761. The views represent the face of the Earth illuminated by the Sun at the beginning, middle and end of the transit. By inspection it is possible to estimate how much of the transit will be visible at any particular place.
