The first drawing of the Orion Nebula M42

[ ](../Pics/More/m42hodierna.jpg)

The first known drawing of the Orion Nebula, created byGiovanni Batista Hodiernabefore 1654 from Palma di Montechiaro, Sicily (Hodierna 1654).

The three stars shown within the nebula are probably Theta1, Theta2 A, and Theta2 B Orionis. They are very probably not the three brightest Trapezium stars, as Serio et.al. (1985)have proposed, first because the stars depicted better match the location of those listed, and second because Hodierna's instruments could have hardly resolved the Trapezium, which he probably saw as one star, Theta1.
