What do you get when you combine the Walters Art Museum's new exhibition, "Heroes: Mortals and Myths in Ancient Greece," and the Baltimore-Piraeus Sister City Committee fundraiser on the night before Halloween? You get one heckuva Greek party.

Guests were greeted by event co-chairs Vasi Karas and Georgia Vavas, as well as the Greek goddess Athena, aka event committee member Gayle Economos - adorned in a golden toga and face makeup.

"This is a place where Greeks feel at home," event honorary chairman Aris Melissaratos said as he nodded toward guests, including: Niki Marsh, Pinewood Elementary School speech and language pathologist; Kali Maheridis, DLA Piper controller; John Diokoulos, Acropolis Construction president; and Darlene Diokoulos, community volunteer.

Folks were encouraged to come in costume, and many followed through on the Greek theme. Mitch Nelson, Rubeling & Associates architect, was clad as a Spartan warrior from his nose-guarded helmet to his sword, shield and sandals.

Irene Derito, Naylors Court Dental Associates hygienist, looked every inch an Aphrodite in a draped white and silver gown and garland.

Meanwhile, Eleni Vettas, Long & Foster real estate agent, came as a cat, with leopard-print ears and feline features painted on her face.

"I was going to come in full [Greek] costume. But I was late getting home from work, and this was quicker. A couple of whiskers will do you," she said with a laugh.
