I'm back from my travels, and while I'm still recuperating (and have an injury that I incurred while doing a lot of walking on Sunday, about 2.5 miles of which was around a library looking for someone!), "full service" can now resume here, as it were.
Today, we've got the festival of Antinous Neos Hermes, which is on the Roman feast-day of Maia, the mother of Hermes. As I was just traveling, and Mother's Day was Sunday, this is a felicitous combination, I think.
The above image is from John Marshall Memorial Park in Washington D.C., and shows Aesculapius and Vesta (a.k.a. Asklepios and Hestia) in addition to Mercury and Maia.
So, celebrate them today in whatever way seems appropriate: practice good communication, and fast communication (i.e. don't put off writing that e-mail to so-and-so!); travel outside your usual boundaries a little bit, invoking the god's protection as you do; honor the matrix (literally and figuratively!) from which the various deities you worship emerges from; and because Mercury is involved, things that involve mercantilism, mercenaries, or even "meretriciousness" might also be appropriate as well (!?!); and so forth.
