The Latin source of abstract, meant literally ‘drawn away’ and is from abstrahere, from the elements ab- ‘from’ and trahere ‘draw off’. The use in art dates from the mid 19th century. Trahere is found in many English words including: attract (Late Middle English) with ad ‘to’; portrait (mid 16th century), something drawn; protract (mid 16th century) with pro ‘out’; retract (Late Middle English) and retreat (Late Middle English) both drawing back; and words listed at train.
