Achillean

Achillean (also known as Men Loving Men (MLM), Apollian, Chaeronean, and Chaeronic) refers to a man, or masculine-aligned person who is attracted to other men or men-aligned people. This attraction doesn't have to be exclusive, as the label is used in a way to unify all men who love other men such as gay (vincian) men, bisexual men, pansexual men, etc, promoting solidarity among men of all identities.

The feminine counterpart to achillean is sapphic. The non-binary counterparts are diamoric and enbian.

History
The word achillean has historically been used to describe things relating to Achilles. The first instance of achillean being used in the context of MLM is likely a 2016 post by Tumblr user Asculan.

Flag
The achillean flag has two blue stripes on the top and bottom representing men. In the center is a green carnation. In ancient Rome and 19th century England green indicated gay affiliations. Victorian men would often pin a green carnation on their lapel as popularized by author Oscar Wilde.

An alternative flag uses a darker blue with a green stripe alongside the green carnation, with the same symbolism.

The original achillean flag had the same two blue stripes on the top and bottom representing men as the current flag. In the center was a realistic green carnation, but this flag was too complicated for many and could not easily be made in vector formats, leading to the creation of the current flag.

Etymology
The word achillean comes from the name of the hero in the Iliad, Achilles, who was romantically involved with another man, Patroclus.
