The data on these pages are completely according to the Madmen database ( http://www.sports-reference.com/olympics/summer/1896/)
In contrast with 1900 and 1904, there is no discussion about the true Olympic nature of the events conducted at Athina in 1896. One event, the 100m swimming for Greek Sailors, is very strange according to later criteria, but it is generally accepted that it may keep its status.
When counting the competitors, it is immaterial whether or not we know their
actual names. In counting the unknown competitors, I have followed Mallon's book
"The 1896 Olympic Games - Results for All Competitors in All Events, with
Commentary", Jefferson NC, 1998.
My handling of the unknown competitors is as follows:
In total, there are 50 unknown Greek competitors, to add to the 176 known ones, brings us to 226
My total of 226 competitors is equal to the number given by Mallon in the Olympdex (176), plus the 50 unknown ones.
