Connect by problems

Question

I'm trying to use the connect by for the first time, and it's not working. I'm running 10.1.0.4 enterprise edition.
Here's the sql to create and fill my table:
create table relTest (id number, parent number, name varchar2(50));
insert into relTest values (1, null, 'a');
insert into relTest values (2, 1, 'b');
insert into relTest values (3, 1, 'c');
insert into relTest values (4, 2, 'd');
When I run a select on the table, this is what I get:
select * from relTest;
ID PARENT NAME
1 NULL a
2 1 b
3 1 c
4 2 d
Which looks right. Then I run a query with connect by, and I only get the following:
select id, parent, name, level from relTest connect by id = parent start with parent is null;
ID PARENT NAME LEVEL
1 NULL a 1
I've tried this several times starting from scratch. Can anyone help me figure out what's wrong?
