Laelaps

Magical dog given as a gift by Zeus, destined to always catch its prey.

Argus

Argus, the Goddess Hera's watchman, was charged with guarding one of Zeus's girlfriends, Io, who was in the form of a white heifer and chained to an olive tree.
Zeus sends Hermes to sing Argus to sleep. After all of Argus' eyes close, Hermes  bashes him in the head with a rock, and takes that hot cow back to his boss.
Hera recycles all of those peepers by putting them on the tail of the peacock.
Ta daa!

The Minotaur

Talk about Jerry Springer material, here's the tale of the Minotaur in a nutshell:
King prays for white bull, as a sign that he has Poseidon's approval to become king instead of one of his brothers.
The bull appears, but the new King refuses to sacrifice it to Poseidon because it's so beautiful.
Aphrodite, to punish the King, casts a spell that makes the Queen fall in love with the bull. The Queen is so in love, that she crawls inside a specially made hollow cow so she can get 'busy" with the bull.
The Minotaur is the result of the mating. 
The Aristocrats!

Hippocampus

The Hippocampus, thought by ancient Greeks to be the adult form of the seahorse.
They pulled Poseidon's chariot through the seas.
On a side note, a lucrative freelance gig helped me to save a nice sum of money.
At an art fair, I saw a fantastic carving of a Hippocampus, like you would find on a carousel. Tempted to buy it, the Voice of Reason told me to use the money instead as a down payment on my first house.
True story.

Scylla

Today's Greek mythological beastie is Scylla. You may know her from the Police song "Wrapped Around Your Finger". 
She was on one side of a narrow strait of water, and Charybdis, a creature that would suck down whole ships in a whirlpool in order to eat the crew, was on the other side.
So, just like being caught between a rock and a hard place, sailors would have to choose whether to lose six of their crew, Scylla had six dog heads that would snatch the men from the deck of the ship, or risk losing everything to the whirlpool.
The stories vary about how this beautiful woman came to be transformed into this monster, but it is safe to say that it was tough to be good looking back then.
Goddesses and other magical beings were very jealous in those days, and often put the smack down on those blessed with straight teeth and clear skin.
Things must have loosened up quite a bit in our times, otherwise Hollywood would be full of monsters.

The Chimera

Today's sketch is one of the most unusual beasts in Greek mythology, the Chimera.
Body and head of a lion, the head of a goat in the middle of her back, with a deadly serpent for a tail.
Fire breathing with poisonous breath and venom, a real beauty of an obstacle for any intrepid hero.

Medusa

Sketch of my favorite Gorgon sister, Medusa.
