The Phaenomena: a work of astronomy and spherical geometry which still exists.
It was well-known to Archimedes who quoted it extensively.
The Conics: now lost, but according to Pappus may have been the basis of the work of the same name by Apollonius.
The Surface-Loci (mentioned by Pappus, now considered lost): may have concerned surfaces of revolution.
The Porisms: a collection of theorems and problems in more advanced geometry.
On Divisions (of Figures) (mentioned by Proclus, lost in Greek but survived in Arabic): concerns dissection of geometric figures.
The Data: elementary exercises in analysis, supplementary to The Elements.
The Pseudaria (or Pseudographemata) (referred to by Proclus, believed irreparably lost): a more elementary primer on geometry.

Euclid Numbers (erroneously so named - such numbers derive from a version of the proof of Euclid's Theorem that he himself never made.).
Euclidean Metric, Euclidean Space and Euclidean Topology.
Several concepts are named after him, but they were so named because they possess properties inherited from concepts which Euclid introduced: Not to be confused with the Socratic philosopher Euclid of Megara. (See Bourbaki for a modern example of this.) It has been suggested that the name Euclid was a pseudonym for a team of mathematicians working as a team. There is controversy as to whether he did actually exist.
He assembled the geometry text The Elements, possibly the most famous mathematics text book of all time.
He taught in Alexandria (then a Macedonian colony, the hub of the Hellenic world).
Greek mathematician about whom little is known, apart from:
