Hammer and Anvil Technique
The hammer and anvil technique for removing flakes from a core is perhaps one of the oldest documented methods. It is quite effective for making large flakes for direct use as tools, or for use as blanks from which shaped tools can be made. This technique entails using the core as a hammer, and striking the edge of the core against a large, stationary rock (the anvil) in order to remove a flake.
Bipolar Technique
The bipolar technique is a modification of the hammer and anvil technique. In bipolar flaking, the core is placed on the anvil for support, and then struck with a large heavy hammer. The compression from both ends of the core cause it to shatter into hundreds of flakes, some of which will be large enough, and of the right shape for use as tools. This technique is often found in areas where the only reliable source of workable stone is rounded river cobbles that are extremely hard to work in any other fashion.
The Early Imperial Roman writers consistently rated Myron among the greatest of Greek sculptors, a sign that his contemporaneous reputation had remained high. The heifer seems to have earned its fame mainly by serving as a peg on which to hang epigrams, which tell nothing about the pose of the animal.
