Question

[George L. McDowell, Jr.]

In Druid Hill Park in Baltimore, Maryland there is a compendium dial which bears the inscription "SINE UMBRA NIHIL." My Latin is not good enough to confirm what I suspect is a double entendre. Could this inscription mean, without torturing the language, both "without shadow there is nothing," and "nothing is without shadow?" Or is there a third possible meaning? Thanks.
