How many horses do you see in this picture? Can you find seven all together? I know - drives you nuts, doesn't it? Click on it and any of the pictures to enlarge them.
Do you see three ships and the rest arches, or all ships?
At first glance, did you see a baby in this one? Look at the whole picture at once, and then the elements within it.
The next book that Eric and I are penning together is a narrative of the events following the Gettysburg retreat, from July 15 through August 1. We have been uncovering a veritable mountain on material on the period, to the time that the armies assumed nearly the very same positions that they had at the start of the Gettysburg Campaign. If Meade was reticent to aggressively attack Lee during the retreat, it's quite a different story over the ensuing weeks. We intend to tell that story (which is heretofore a large gap in the scholarship of 1863), give our readers enough to form their own opinion, and help them see the whole picture.
In the end, sometimes it's enough to spin your head, and we realize that. Look at this picture:
Now, like it says, focus on the dot in the center, then slowly move your head back and forth (closer then further away) and see what the outside circles do. Sometimes we look at this picture for what it seems to be, then it changes when our perspective changes. Likewise, evidence seems to tell us one thing, then what we "see" changes with our perspective - looking closely and then stepping back for a bit.
Sorry if I gave you a headache. But sometimes that's the job of researchers and writers. Take two aspirin and read my next book.
